Now let me get one thing out of the way first. I am not a
Marvel Studios Hater. I have liked a majority of the films made by Marvel Studios. Thor The Dark World being the obvious exception. I'm just here to give a few reasons as to why i'm really really worried about the future of the MCU and it all comes down to the two Russo bros. Now once again before i list my reasons i don't hate the Russo bros, those 2 are good directors. But there are a few things that might happen if they have the level of involvement they seem to be getting. Quite frankly even if Joss Wheadon got this level of involvement i'd be worried. But enough of the introduction lets get down to buisness.
1. The Quality Of Avengers Age Of Ultron

Now this is something i'm not as worried about as the other things on this list, as the trailers for the movies and what we've heard so far has been promising. However hearing that the Russo brothers will be directing the third film in this franchise is sending a little chill down my spine. Now there could be several reasons for this, A. Marvel just thinks the Russos could be a better choice for the story they want to tell, which could be true, but with how big and cosmic the infinity war story is i doubt that would be the case as the Russos haven't directed anything yet that would give Marvel that impression. Then there is the option that could be the case and its what worries me B) Wheadon really dropped the ball with Avengers AOU. Now this could just me being overly worried about nothing but compare this to some other films. Usually when the studio feels that a director has done a good job with a film in a franchise, even before the film comes out they will sign them up to do the next one. They did it with Joss around the time of the first avengers film. Marvel may have seen whats been done with AOU and not liked what they see, or Wheadon could have pulled an Alan Taylor, we honestly don't know. All i'm saying is, that if they don't want Wheadon back, i'm not sure if Wheadon had the mentality of "Save the best for last".
2. The Russos may play favoritism. Even if its accidental.

This is one of my biggest worries with these guys taking over The Avengers franchise. One of the biggest things with the Avengers is that every character (for the most part) feels equally important, everyone gets their time in the sun, hell even in the first Avengers film (for the most part) the characters got equal screen time. What i'm worried about is the fact that the Russos will have directed not one but two Captain America movies by the time they would have to work on Infinity War. By the time they would get to that film Cap would be what i would call their "Comfort Zone". Its a character they have worked on in the past so they feel more comfortable in his world and with that character, and due to that Captain America might become the central character in a franchise where every character is supposed to feel central. Since Cap is a character they have worked with before he may be the one getting all the cool moments, leaving a lot of the other characters in the dust. Now of course my opinion on this could change depending on how Civil War plays out. If they are able to give Cap and Iron man equal importance to the plot then this worry will go away. But for now I have this feeling in the back of my neck, and it won't go away. This would apply even if Jon Faverau directed Avengers, since he had worked on the Iron Man character before.
3. Burnout Part 1 (The MCU as a whole)

Oh boy, this is the biggest worry i got. In order for a franchise to stay fresh and keep a leg up it needs new blood every once and a while. Usually that would apply to only one series of movies but in this case the MCU at least as seen by most people is all one big franchise. Every movie in the MCU at least so far has been a superhero action movie. After a while a director or directors in this case just get tired of doing the same thing over and over again. With the Russos brothers they arn't even doing 3 movies for marvel, they are doing 4 and possibly more if the rumors are true (which i will get into later). Look what happened to someone like Sam Raimi in Spider-Man 3. When the 3rd film of the franchise came around he was tired, and the film majorly suffered for it. That same thing may happen here, even though The Avengers has a series of different characters all of the films we know they will be working on will have at the very least Captain America, Nick Fury, Black Widow, Maria Hill and Iron Man. After a while those franchises could blur together, fatigue could start to set in, and as a result Avengers 3 and any film they direct afterwards for Marvel could dip in quality. Especially if they will be writing a lot of those upcoming movies. Directing a movie is enough of a job but then to also write for that many movies in such a short amount of time could drive you crazy.
4. Burnout Part 2 (Spider-Man)

Now this last bit is something that hasn't even been confirmed yet. But according to some rumors that have been floating around if Marvel Studios were to get the rights to Spider-Man back in this deal they would want the Russos to tackle the new trilogy of films. I personally feel this is a huge mistake. Yes they are good directors. However with what i brought up earlier we don't know what could happen, how sick they could be of making superhero films. Spider-Man more then any CBM franchise out there right now needs to jolt of new life into it especially after how people reacted to The Amazing Spider-Man 2. Now working on Spider-Man could be a breath of fresh air, it could end up feeling even more tired then before due to the directors having worked on these types of films for that long. Sure. Spider-Man is a very different character then Captain America or Iron Man or Nick Fury. However Marvel films do all share a similar tone for the most part, they all have to feel like they are in the same universe, and that might just be enough to make spider-man already be dead in the water before the film even arrives. We need someone new that marvel would bring in. Sony apparently wants Phil Lord and Christopher Miller, if marvel were to get the rights maybe they could bring them in, cause then at the very least they would have a fresh perspective on how to work with the movie. But we will just have to wait and see with this last part as it is all just a rumor.
Now of course like i said, this is just me rambling about something that has been bugging me to a point, i know not everyone will agree with me (hell i don't expect any of you will). But i'm hoping at the very least you see my point, and why I'm not as excited as i would like to be for the future. Why i am staying a bit cautious as to whats coming up. Thanks for reading and have a great night everybody.
