I think you forgot Batman's joke.Lord Beautiful said:The only ending that comes to mind is the ending of Onimusha 2. My god.
As for your example, it could be made forgivable if they made but one minor change.
Had Batman dragged Joker's carcass by the cloth of his collar out of the building as opposed to carrying him lovingly in his arms, I would have thought far better of it. He's a murderous, remorseless psychopath who does not deserve the reverence he receives. He's exceedingly well characterized by both the writing and the acting, certainly, but his death is not a tragedy; it is a blessing.
Batman said:You want to know something funny?
Joker said:What?
Batman said:Even after all of this I still would have saved you.
Joker said:Hey, you know what, that is pretty funny.
OT: Limbo. I just finished it and boy how that ending is such bull. I know that the game has no story or whatever and is all edgy and really pretentious, but that ending just made me go " Really? You're really going to end like that. Well okay... Fucking Danes."
