In the comics, Bane wears the mask to dispense the super-steroid Venom (to which hes addicted, leading to debilitating withdrawals if not constantly administered). In TDKR, Bane wears the mask in order to receive a constant dosage of anaesthetic to halt the agony of an injury sustained in prison. How then, Im led to thinking, is he up and walking around? Surely this agony hes medicating is some serious internal injury? Surely theres a better way to address this than engineering an anaesthetic mask, morphine addicted quack or no. Why didnt he address the injury upon his freedom? Or even have the anaesthetic adapted into some injection based form purely because mask based is ridiculously inconvenient? Too many things about Bane, about the entire basis of his character, just do not add up. The changes haven't achieved anything I'd consider grittier or more realistic than his comic counterpart, in fact they're about on par with the original Bane's medical realism. Now Im not one of these guys who says its not like the comics, I hate it. I know Nolan has tried to take away some of the gaudier elements from the comics in place of a more real-world envisioning. Thats fine. But when your changes start to make even less sense than the source material, theres a definite fault in logic.
