My only regret now is that we don't get to see the Riddler in Nolan's universe.
Just imagine Leonardo Di Caprio in the part
I still can't quite put my finger on it, but I felt something was off about Hathaway. She didn't seem to have very good presence, and her character didn't really feel necessary to the story (aside from being the catalyst to get Bruce to become Batman again).
Nolan does tend to cast against type, plus he tends to cast young-ish looking people. And personally, I don't think any big-name actress right now really makes for the ideal Catwoman. Maybe that has something to do with it. She still exceded my expectations though.
