Re: Bane... The new Darth Vader?
Well considering Nolan himself said The Joker was sort of like their "Hannibal Lecter" and they wanted "more of a Darth Vader" for the villain in TDKR, it's pretty understandable why people make the comparisons.
And I always thought of Shredder himself as having shades of Darth Vader.
I also see the parallel in that both characters have a "religious" background of sorts which they became separated from (Jedi/League of Shadows) but are also essentially military commanders.
