Too far? Too far?! Bane is the man that masterminded the breakout of Arkham Asylum and broke the Bat; the one man that, for many years, put away Gotham City's most hardened and dangerous villains, criminals, and thugs.
From a comic stand point, it's "unrealistic" to believe that a monster like this only broke Batman's spine instead of utterly demolishing him.
From an overall standpoint, this is every inch the muscular, steroid abusing, cold and calculating monster that Bane should be. And the only thing that makes all of that power even more horrifying is the brains behind it.
Bane should be, for all intents and purposes, the one villain that should truly scare Batman, and this is it! So I say that this is a fantastic representation of the man, monster, and mastermind that is Bane!
