The only two reasons why Michelle seems to have had more to work with, was because she was written as a loose-canon. A total nutjob having a nervous breakdown, which of course allowed Michelle to dig deep into those few scenes. Secondly, she was far more sl**ty than Anne's version. Both sexy, but in different ways.
You can be sexy without acting like a tramp.
There is something to be said about a full-on origin story shown on film. It connects that character/actor to the audience more than anything. People will always love Reeve more than anyone else. Maguire (unless Holland plays the character so many times that it sticks with everyone longer). Bale, as far as Bruce Wayne goes, will always be loved the most. Downey. Origin films that are done well of course.
Surprised Bale smoked Affleck and Keaton so hard in that poll. Holy crap. But goddamn, why did 29 percent vote for Halle Berry as the best Catwoman? Jeeeeezus.
