So, after reading 8+ threads about BvS/DCEU, I've come to draw the conclusion that DC/WB simply do not give a shit about the characters they are portraying on the silver screen.
Jimmy Olsen? Fuck him, shoot him in the head and only acknowledge his existence in the closing credits!
Lois Lane? Make her completely incompetent and uncompelling!
Batman? Why not make him a remorseless murderer? That works, right? (Wrong)
Superman? Let's kill him in his second movie, before he even gets to establish himself as a superhero of truth and justice and compassion because he totally isn't pivotal to the entire DC universe, especially the Justice League, right? Right? (Also wrong)
Lex Luthor? Totally an insane, incomprehensible psychopath that more aligns with the Joker, that works, doesn't it? (No, it totally doesn't) Well, fuck you, we only need him for this one movie, because we kill Superman anyways!
Doomsday? We can totally treat him the same way Fox treated Deadpool in X-Men Origins: Wolverine, and people will be totally okay with that, won't they? (Noep, did you not see how pissed off people were with how they treated Deadpool in that movie?)
I mean, honestly, for all the flaws of Man of Steel people point out, I thought it was a fairly decent movie. Superman was just starting to try to find himself and who he was, and Zodd put him in an impossible position, because here was a seasoned military veteran who was like a God to the people of the planet earth who wanted to terraform the planet and murder every single human being on it, and the only person who could stop him was an equally god-like being who was taught that he should suppress his superpowers and act more human. Yes, there was a lot of collateral damage in their fight, but he was literally the ONLY FUCKING PERSON ON THE ENTIRE PLANET who stood a chance at stopping Zodd, and he did so through the ONLY option available to him: Direct combat. Yes, likely a couple hundred to a couple thousand lives were lost in their fight, but the alternative was EVERY SINGLE HUMAN BEING ON THE PLANET DYING if he did not fight, or fought yet lost.
Given that, the fact that Batman, portrayed as a remorseless murderer, saw Superman as a threat because he ended an actual threat in the only way presented to him and was the only one capable of doing so, is just fucking absurd. The fact that a completely insane psychopath could goad him into it is even more absurd.
I mean, seriously, what DC/WB should have done is made a Batman movie, where Ben Affleck establishes himself as Batman, then made another Superman movie, where Superman realizes just how vulnerable humanity is and just how much he can do to protect them after the events of Man of Steel, and establish Lex Luthor as a serious rival, then, with Suicide Squad being a thing, make their antics so big that Batman and Superman have to join forces to stop the mayhem the Joker compels them to cause with Wonder Woman thrown in the mix, signaling the beginning of the Justice League, and build from there. Creating a Batman vs Superman movie where Batman is a remorseless killer, Superman is a superbeing with questionable morals and Lex Luthor is a psychopathic plot device there solely to initiate the conflict between the two and where Superman dies at the end just seems like an all around terrible decision that completely undermines any future attempt to build a Justice League.
TL;DNR: DC/WB seemed to crap all over its characters and doom their venture into creating an extended cinematic universe right from the get-go in the process. As such, I see little hope in their venture becoming a success in the long haul, because they completely screwed the pooch with BvS.
