After the success DC had with the Death of Superman storyline they decided to use their other mainstream creations in character altering storylines; Green Lantern Hal Jordan was used in Emerald Twilight and Batman was in the Knightfall story arc. By far this is the best of them all.
The main story consists of a new villain emerging in Gotham in the form of Bane. Bane wishes to take control of Gotham and to do that he must go through the one man who will be standing in his way. At first I was not so sure about Bane, I admit that this is solely down to the embarrassingly awful Batman & Robin film, but after reading the first part of the story my opinion had changed completely. Bane is truly one of the most memorable villains I have ever read, his physical presence on each page and incredible mind are really amazing.
Bane realises that to take Batman on is foolhardy so devises a plan to release all the prisoners within Arkham Asylum; with the ensuing chaos Batman singlehandly attempts to bring them all to justice himself, all the while Bane is looking on learning all about his adversary.
Facing opponents like, Joker, Scarecrow, Mad Hatter, The Ventriloquist and more, Batman brings himself to the verge of collapse and exhaustion. Sensing the time is right Bane makes his final move.
The main power of this story is not about Batman vs Bane, in my opinion it is all about how Batman will take himself to the verge of death to protect Gotham and fight crime to enable people the upbringing which was stolen from him. And we see the effects that this chosen path has had on him.
