So far with the movies :- the first film with Michael Keaton as Batman/Bruce Wayne.
The thing I did not like about the following films was the fact that there was 2 bad guys competing with each other.
And with Batman Forever and Batman & Robin, it really comes down to Joel Schumacher's $#!+y directing. Like he f**ked up BANE!!! He was a batman worst villian. (like Vemon for Spider-Man), and they turned him into Poison Ivy's Gimp.
I do look forward to Batman Begins.
