Translating the comic book format to the big screen is a difficult task for no other reason than the comic book offers months or years of careful character development and story telling. The Bane story is quite complex and the concept of mentally and physically breaking down batman (as was done in the comic book) over several weeks would be near impossible on the big screen. Nolan and co. have succeeded in taking some of the best elements of the Bane story and crafting/combining them with other comic book canon (Ra's Al Ghul and his daughter for example) to create a completely compelling and satisfying story for both the comic book set as well as the larger, general audience. No spoilers, but the ending is by far the most fitting premise that could be done with the options given. Possibly the best of the three and a fitting end to a landmark trilogy of films.
