My biggest problem with the introduction of Batman into the DCEU was that he was far too violent and brutal for reasons that weren't exactly explored in 'Batman v. Superman: Dawn of Justice'. Comic-book readers understood that Snyder took inspiration out of 'The Dark Knight Returns' and even 'Batman: A Death in the Family' when giving us this Batman. Unfortunately, non-comic book readers weren't familiar with these stories and as it so happens, most of the audience that go to watch these movies aren't necessarily huge followers of the comics.
For us to care that Batman had recently suffered the loss of a Robin the audience has to at least be somewhat properly attached to their relationship to care. So what do you do in this case? Simple, make a Batman and Robin movie in which we see Jason Todd taking the mantle of Robin and this would be after the events of Dick Grayson leaving Bruce and going to work on his own in Blüdhaven. This way we can have subtle hints at the existence of Dick Grayson and that we know the Bat-family is growing in the DCEU. More so, it leaves room for development for all these characters rather than simply saying that one is either dead or the other is God knows where.
The villain of the movie should be someone who can challenge both Jason Todd and Bruce's relationship and so of course the villain we think of when thinking about Jason Todd and Batman is Joker. Yes, you can have Joker in this movie or you can leave that for the sequel to the Batman movie instead of killing Jason Todd in this movie. Develop the character properly and take time so that the audience feel the relationship between Jason and Bruce is genuine. So who would the villain be? Hush.
In the comics, Hush is the childhood best-friend of Bruce Wayne, they grew up together and the two had trusted each other immensely. Immediately this allows for the villain and hero to have a personal attachment and would make for a more compelling story than having some other villain that doesn't really provide that attachment. This way we can also have flashbacks exploring Bruce's childhood with Elliot. Thomas Elliot (Hush) in the comics blames Thomas Wayne for ruining his life by saving the life of his mother as he previously attempted to murder his parents. As such, he seeks to take revenge by ruining Bruce's life and eventually killing him.
So how would Hush make a compelling villain for a Batman/Robin story... well, in this movie Jason is still a kid, maybe about 13-16 and as such, he is easily influenced or at least he is more naive than he would be if he was a bit older. This means that Jason is more suscepitible to listening or even believing any lies that Elliot may feed him about Bruce as he would attempt to take away everything from Bruce, starting with Jason.
We get a conflicting story between these three characters and it all falls onto who Jason trusts more, Bruce - the guy that is training him, looking after him and caring for him or Elliot - who knew Bruce since they were kids and knows the type of man Bruce could be (obsessive, dangerous and scary). Ultimately this movie would test everything we've seen between Bruce and Jason until a decision is made that Jason would stick with Bruce.
The movie would also give Batman a chance to show a different side to him and it's that he is worried for Jason because he cares. Of course we've seen that in comics and the animated shows/movies but we haven't seen it done on the big screen. This would even be a good way to set up the entirety of 'Batman: Hush' storyline through the sequel or a complete trilogy if they wanted, meaning we get to see different Batman villains appear. If they don't want it to be a complete trilogy but have a 'Batman: Hush' storyline in the sequel, that's fine too. The trilogy could end with the death of Jason Todd in which we would then have Joker as the main villain. This way the relationship between Jason and Bruce is heavily developed by the third movie, we also see that Bruce is affected by having to fight his only childhood friend and then eventually it would all lead to Jason dying.
That's when we would have a Batman that feels helpless but angry at the world, he feels the world has taken everything from him as Dick has left him, had to fight the only friend he ever had and loses Jason Todd. He would feel guilty for even allowing a child into the battlefield and now it would make sense as to why this Batman is so angry and vengeful towards the world. Now, I know that this would take away from how 'Batman: Hush' occurs in the comics but so what? Movies and comics don't need to be the exact same and if the story-telling is well done, that's what matters. I know that by making this type of story arc for Batman, it would then tarnish any possibility of having 'Batman v. Superman: Dawn of Justice' take place and honestly that's okay. We can always have a Batman vs Superman story arc in another way and that's what my next article will focus on. My third part of this article will be my final and will focus mainly on how a team up movie can lead to a Batman vs Superman movie.
