I'm sorry I care about comicbooks
The Mexican wrestling mask is part of Bane's identity. He grew up dirt poor and in a crappy mudhole, yet bettered himself. This Bane's accent reeks of highly educated, prep school melodrama (Bane was smart make no mistake but self made) that is at odds with whom he is. He should be a hard luck case Latino that crawled up from the sewers and jail, guilty from birth yet strong enough to rise above it all and empowered himself to be one of the greatest strategic minds. Here is a guy that knifed a dude in jail with a shank hidden in a teddy bear when he was a kid. He fought for his life everyday growing up. He meticulously trains his mind and body not wanting to fall back into that despair and fear. He pits himself against Batman just to see if he has what it takes and makes it his mission in life to best him, his purpose is to validate himself over the Bat's broken body. From what I have seen this Bane pisses all over that legacy.
It's not the Bane I want to see. Yes I get pissed off at comic book (DC especially) movies as much as I do hollywood anime movies. If you all like it, go ahead and like it, leave me to stir my hate pot though
