^You raise a lot of great questions at the end of your sentiment there. Ultimately, I think a third Burton film would have brought everything full circle. Obviously with trilogies certain things need to either be tied up, explained, or extinguished. I think a third Burton/Keaton Batman would've answered a lot of questions.
I definitely agree which is why I'm glad we're finally getting a Batman trilogy with the same actor and director throughout all 3 films.
Schumacher, well, let's just say I don't even acknowledge his films as existing.
This I have to disagree with though. Whether it was deliberate or not Schumacher's
Batman Forever managed to give a resolution to the arc that began in Burton's
BATMAN. What sucked was that since Burton/Keaton didn't get one more shot it just didn't flow consistently but it was still there.
Bruce Wayne in 1989 was a tortured soul all his life he thinks "if I had not asked to go to the movies my parents would be here today." That's why he always visits crime alley and always keeps re-reading their case files. He's obsessed with their death and consumed by guilt in many ways he's still that 8 year old kid just very repressed and angry.
You could understand why he would completely flip when he finds out the person he feels is responsible for cursing his life, his parents murderer. At that point his obsession changes from his figuring out his parents' murderer to resolving their murders through the means of revenge. That's why he becomes a savage by the third act all his rage has been amplified by the fact of who Jack Napier really was.
By 1992 it is apparent that vengeance simply wasn't enough. He's still driven by guilt and if anything finding his parents killer just made him more barbaric and consumed by his demons. He still feels that there are hundreds of Jack Napier's out there. His mission is to stop crime at any costs even if he has to play dirty to make a point and get closer to achieving that goal. All he lives for is to guard Gotham City, he made a promise in 1989 that if the forces of evil rise again to call him through his signal. He hasn't forgotten that mission but he has just gotten more extreme in trying to accomplish it.
At this point why should he even show sympathy, these dark souls don't show sympathy to those they victimize. That is until he meets and falls in love with a victim turned criminal, Catwoman/Selina Kyle and sees that he may not be that different from the criminals he faces after all. He sees how Selina's thirst for revenge has driven her to a point of duality and obsession that she can't no longer turn away from. How she became so consumed by her demons that it has made her completely apathetic and wreckless. Catwoman is the real Selina as much as Batman is the real Bruce.
Because of her tragedy he sees a self reflection there that makes him conscious of how out of line his methods have gotten up to that point. How he has become so consumed by his guilt and the dark point that caused it that he has lost a grip on his humanity. That's when he starts rethinking things and tries to right wrongs by helping her along a path of redemption. Not just to redeem her but also to redeem himself.
This is why he's sending Shreck to jail instead of going more extreme, he doesn't care about ending his life as Batman thus the unmasking in front of Shreck because he feels he has found a true equal for himself and wants to give the both of them a chance at a normal life again. The problem is she rejects him, for all his trying he has failed. No matter how bad he wants to change things just are the way they are because they must be that way. Selina will always be Catwoman for the same he reason he must always be Batman, it's just who they truly are.
Not redeeming Selina in his eyes though and failing to bring closure and filll his emotional void is another element of guilt that will haunt him until he's cured by the end of Shumacher's first film. Now I won't get into
Forever and how it resolved everything through Bruce and Dick's relationship as well as Bruce going to therapy but there are plenty of posters here who could do that.
