Uhhh what? If you're referring to Obadiah Stane's giant metal suit, that's Iron Monger from the comics.
Ah, you're right, my bad.
Well I think everything they did so far was a gamble and I dunno how it has been fitting with continuity but seriously fuck it. At this point they've got enough fans that aren't comic buffs and I think the only reason this films are so popular is they do break the mold. So I really wish they'd keep doing that and create a character instead of plucking another. I think one of the biggest problems with these movies is that they are Batman movies and it limits them in a way, and maybe they'd never have had the same success with a completely original character as they are having now but I think they'd have made for better movies honestly.
You make a good theory, but I honestly don't know how it would turn out in practice. Making up characters, villains at that with movies like this is seriously putting all your chips on the table, considering that this is the third one, and
especially considering how well received the Joker was. I don't think Nolan wants to fuck that up.
Besides, there's still Bane. Seriously,
Bane.
