11 Comic Book Movie Characters Who Were Killed Way Too Quickly
6. Ra's Al Ghul
Okay, so maybe it didn't fit Nolan's "more realistic" Batman to have Lazarus Pits and immortal characters, but given how little David Goyer and the Nolans seemed to care about preserving simple logic in the final Dark Knight movie, it shouldn't have been too much of an issue to bring in a little of the supernatural to the franchise as a nod to the source.
The pursuit of realism in a comic book universe that so keenly relies on supernatural elements - this is after all a character born on principles of fear - is a fool's gambit, and one that limits how closely you could adapt the comic book, and Nolan's resistance at times felt a little like bullish commitment to his own agenda to the cost of fan service.
The result was that his Batman films aren't really Batman films in the purest sense (no matter how great they were as a trilogy) - after all, James Bond, Indiana Jones or Jason Bourne could probably have swapped positions with Batman and the films would still have worked.
Nolan should have defied expectations - as some thought he would - by actually bringing in the Lazarus Pits, and having a more traditional portrait of the League Of Shadows' leader would have been far more fitting than having him appear as a plot-developing hallucination that basically allowed Bruce Wayne to learn helpful facts from his own imagination.
