5 Bad Decisions In The MCU We'll NEVER Be Able To Forgive Marvel Studios For

Marvel Studios has delivered more than enough great moments for fans since Iron Man was released in 2008, but a handful of mistakes have been made since then that we still aren't over. Check them out...

Since Iron Man blasted into theaters way back in 2008, Marvel Studios has changed the game for superhero movies. Of course, not every movie or TV show they've released has been perfect, and, yes, at least a few of them could be considered downright bad. 

Overall, though, the MCU has an impressive batting average, knocking these adaptations out of the park time and time again. Still, we'd be lying to say that some significant creative missteps haven't been made along the way, and it's those we're taking a closer look at today. 

These aren't poorly conceived cameos or the odd instance of taking one too many liberties with the source material. No, these were franchise-altering missteps that, had they not happened, could have made the MCU even better. 

Will you agree or disagree? Well, you can check them out by clicking the "Next"/"View List" buttons below...
 

5. The Falcon Became Captain America Too Soon

Fucedv9f o

Captain America: Brave New World didn't live up to expectations, and arguably failed to establish Sam Wilson as an effective Captain America before he takes centre stage in Avengers: Doomsday next December. However, mistakes were made long before that. 

While we have no problem with Sam wielding the shield, it should have been Bucky Barnes. Not only would that have followed the comics, but it was a logical next step for a character who had finally found redemption for his past actions and could now honour his best friends by inheriting his mantle and the expectations and pressures it entails. 

The former Winter Soldier would've come out the other side an even richer character. Instead, he was a Senator for 5 minutes and now leads the New Avengers (which, we guess, is something). Both Bucky and Sebastian Stan deserved better and have instead been left to tread water.
 

4. We Never Got The Kree/Skrull War

8ttuz5pv o

Handled the correct way, the Kree/Skrull War is a story that has enough meat on the bone to be the basis of an entire Avengers movie. At the very least, we'd have liked to see the conflict form the basis of a Captain Marvel trilogy. Alas, too many creative missteps were made in 2019.

The heroic Skrulls...the '90s setting...Yon-Rogg's disappearance...The Supreme Intelligence being dispatched in a throwaway flashback...this all went wrong in so many ways. The way Marvel Studios dropped the ball on the conflict remains downright baffling. 

It's a shame, too, because there's a great war movie somewhere with Carol Danvers fighting both the Kree and Skrulls in a battle with the fate of the entire galaxy at stake. After Secret Invasion (another waste) and The Marvels, it's sadly too late for that to realistically come to fruition. 
 

3. Kang The Conqueror's Downfall

Ruz97rzb o

There's a weird narrative online now that the Multiverse Saga's big bad, Kang the Conqueror, was beaten by ants. That's not entirely true, of course, but wasting this villain in Ant-Man and The Wasp: Quantumania remains a moronic move on Marvel Studios' part. 

Kang the Conqueror was the baddie we were meant to fear; the "final boss," so to speak. Instead, he was relegated to this messy threequel and ultimately dispatched by Scott Lang and Hope Van Dyne in an underwhelming fight, which was the product of reshoots. 

Now, we don't doubt there was a bigger plan at play here. In fact, it's been said that his apparent demise was meant to set the stage for Kang to return more powerful than ever before. Jonathan Majors' legal issues aside, this was the wrong place to debut the Conqueror and a real waste.
 

2. The Avengers Was Missing Two Founding Members

J4yho4v3 o

We can't fault Marvel Studios for waiting on Edgar Wright to make Ant-Man, but doing so meant neither Hank Pym nor Janet Van Dyne were founding members of The Avengers. 

Black Widow and Hawkeye took their place, one of many cues the studio took from The Ultimates. Those two made for effective members of the superhero team, but Ant-Man and The Wasp's absence still stings, and is the main reason Tony Stark and Bruce Banner become Ultron's creators.

Ultimately, the decision was made to age up both characters, meaning we never got to see them in their prime. We love Scott Lang and the newly created Hope Van Dyne; this just feels like a missed trick in the MCU, and one that's robbed us of many great stories and moments. 
 

1. Planet Hulk Became A Subplot In A Thor Movie

V1z7arkr o

While we can appreciate that not everyone enjoyed Thor: Ragnarok's zany tone, the movie as a whole was very good (and vastly better than Thor: Love and Thunder, a follow-up which nearly earned a spot here for its crummy take on The Mighty Thor). 

Making The Hulk a supporting character in a movie and essentially rebooting the God of Thunder was a wise move for a character who couldn't headline his own project at the time. Still, condensing the "Planet Hulk" arc to a glorified subplot was disappointing. 

So much of what made that story beloved was gone, including an ending which set the stage for World War Hulk. The Green Goliath never found romance, didn't get a team of his own, and was largely reduced to being involved with jokes about the "Devil's Anus."

@HashTagSwagg - I’m surprised “Flaptain” isn’t a more commonly-used moniker for Sam in his work clothes.

Pretty much everything regarding Hulk was a bad decision.

Say whatever you want about FaTWS and/or BNW , I think Sam as Cap was one of the best things about the latter especially…

The movie definitely had its issues and was the weakest of the four cbms this year but I felt Mackie & by extension Sam really settled in the role well and felt confident , commanding & charismatic in that role.

Yes , he’s a different Cap then Steve in terms of his skill set and how he may do things but the values are the same.

I have liked him as Cap and hope he stays in the role beyond SW aswell!!.

I loved Ragnarök overall, but was definitely disappointed by how quickly the nod to Planet Hulk was brushed off. Not to mention just how silly it got at times, even by MCU standards. Planet Hulk is easily one of Hulk's best stories and a great insight into the character outside of just getting angry and smashing shit.

@ModHaterSLADE - Yeah, but we never really had much getting angry and smashing shit to begin with.

Killing Quicksilver in his first film is something I have never forgiven Marvel Studios for. Not when the studio is touting a multiverse story in which they have easily brought back characters or actors back. How many versions of other characters have we seen get their shot back into the MCU? I'm hoping Secret Wars fixes that mistake but I'm not holding my breath.

Spike101 - 11/13/2025, 4:58 PM
@String - yep that another one better than most of this list.

Are there really people who mad at a company that they will never forgive them?

Must be dope to have so little responsibility that this stuff eats away at you.

@thedrudo - very little logic in what you just threw together there my friend.

Where is Taika Waititi on this list....he should be number 1
Forthas
Forthas - 11/13/2025, 3:58 PM

Here are five more...

1) Fake Mandarin
2) The mini-musical number in The Marvels
3) Banner is unable to transform to Hulk because Thanos manhandled Hulk
4) Killing Aunt May
5) Thor Love and Thunder
McMurdo
McMurdo - 11/13/2025, 4:10 PM
@Forthas - also Strange ruining reality for a bratty kid. Botching the Scarlet Witch. The list is almost endless.
Spike101
Spike101 - 11/13/2025, 5:03 PM
@Forthas - fake Mandarin is unforgivable, Ben Kingsley is such an amazing actor and he captured the scary, cold, brutal side of the Mandarin so well. What a waste of both character and actor.
Spike101
Spike101 - 11/13/2025, 4:05 PM
Screwing up Hank Pym and the Mandarin twist are better candidates for this list I think.
HeavyMetal4Life
HeavyMetal4Life - 11/13/2025, 4:21 PM
The only ones on here that I'd really agree with are 3 and 4.

I have a theory that the cómic creative comitte (Brian Bendis, Joe Quesada, Alan Fine etc.) was what kept the writers from 2008 to 2016 from going wild with the changes to the characterizations, another factor was that imput from people with cómic book background Like Josh Whedon, JMS Strazinki,Craig Kyle and Cristopher Yost, but that control was seen as an anoyance for the directors and screenwriters who want to do "thier own thing" that's how we end up with inferior takes on storylines like secret invasion and the fast foward of the legacy charaters.
HelloBoysImBack
HelloBoysImBack - 11/13/2025, 4:51 PM
My list

IM 3 Mandarin
Nerfing hulk
Scott lang instead of Hank Pym
Hank Pym and Janet Van Dyne not part of original avengers
Killing Iron Man Quicksilver and Black Widow
Taika Waititi
Not spending more time on Asgard
Cutting Captain America and replacing him with Walmart version
Replacing Norton with Ruffalo
Not seeing Spiderman in NYC so far
Not replacing Chadwick
Somehow making the cleverest people in the MCU female and black
Multiverse too early

@HelloBoysImBack - that pretty much sums it up 👌

@Spike101 - did I forget any
Spike101
Spike101 - 11/14/2025, 2:56 AM
@HelloBoysImBack - maybe Tony inventing Ultron rather than Hank, and Yellow Jacket being an entirely separate character but you have listed Hank. This whole mess to me is by far the worst atrocity.

The whole Marvels movie start to finish.

Not going with Norrin Radd.

Way too much childish humour.

Agatha Harkness beginning to end.

The Leaders head.

And overall making a complete mess of the build up to Kang.

Spike101
Spike101 - 11/14/2025, 2:59 AM
@HelloBoysImBack - oh and I nearly forgot Namor who looks nothing like Namor!

deamon - 11/13/2025, 5:33 PM
They are going to do same with most Marvel popular character, Spider-Man.
Peter Parker isn't even adult yet, but they are trying to push Morales in next saga, way too early.

@deamon -

Of course they will. Stupid radical liberal virtue signalers make stupid decisions. It’s how they will kill the Spidey golden goose.

5. Didn't need to at all, not a question of "too soon".
4. Would have maybe been a bit boring. Skrulls aren't that interesting. And Kree they did without a proper Mar-Vell, so nah.
3. A good Avengers foe on the page, not sure about movies where there is only so much time to tell a convoluted and messy history.
2. If any original Avenger wanted ditching it was Hulk. Poor fit in comics and film.
1. Don't care.

The thing "I'll never forgive them for" more than any of the above, what they did (or didn't) do with Thanos, Mar-Vell, Warlock, Death etc. The Russos thought they knew more about Thanos than Jim Starlin. and they got away with it at the time because they were riding high on a wave of popularity. "This would be some great if it was on TV or a film" said me as a little kid in the 1970s, knowing even then that it probably never would be... and then decades later OH! THEY'RE ACTUALLY DOING IT!... and then the terrible disappointment that it was so changed...! Very strange feeling with Thanos becoming a household name with "normals" who didn't even know he'd been in a comic, let alone in the 1970s.

Forgive me, but I completely agree with his take on these 5 huge screw ups

There have been many more.

None of these things bothered me. Especially Falcon becoming Cap. Cap was done. He's not going to run around playing superhero at 195 years old. Yes, 195. MCU Cap was born in 1918. Endgame takes place in 2024, making him 106 years old. He goes back 79 years to 1945, then reappears in the present after having spent those 79 years living a life with Peggy, making him 195 years old when he passes the shield to Sam.

At any rate, he couldn't give it to Bucky because Bucky, to borrow a phrase from Black Widow, had too much red in his ledger. He still had work to do. He wasn't ready, mentally. He says as much himself in The Falcon and the Winter Soldier series. Sam had proven himself to be a good and moral man, and a great soldier in his own right. He was the clear choice to be Steve's successor. Too soon? No. Steve had 79 years to mull it over. It was time.

#5 (Cap/Falcon): I mean, sure, but it was a good decade until the switch.

#4 (Kree-Skrull War): Agreed; wasn't geeked up for it, but wanted to see it truly come to a head.

#3 (Kang the Conqueror): 💯 beyond words and I still haven't gotten over it, might not.

#2 (Founding Avengers): Can't even blame them for this, and I didn't really care anyway, they did marvelous (heh, heh) with what they did have at the time.

#1 (Planet Hulk/Ragnarok): Uh... yes and no. I really wish they had managed a World War Hulk before Smart Hulk though.

Agree with Pym not featured first. Scott could have been introduced later. I think they allowed the story they wanted to tell to dictate the character they wanted. Scott. His story could have come later during maybe in the 3rd Antman movie.

Secret invasion is unforgivable. That's a full scale blockbuster movie. What happened to that Superscrull after that story?

Have no problems with who they cast as Namor. He embodied Namors character. Just take off all that jewelry and accessories going forward.

Kree/Scrull war. I thought would be Captain Marvel 2 when she left for so long. Definitely needed that story. And Mar Vell could have been shown as the first CM with that title believed to have died of cancer and Carol trying to live up to his legacy. Though I would prefer that he survived somehow and we could see some of his adventures.

The living tribunal granting wishes in Thor L&T?

Actually liked Agatha series.

Forgot about Quicksilver. Did they kill him off because his powers could solve many challenges easily and they wanted the Avengers to struggle more?
