I have to agree that the first two films done by Tim Burton were excellent.
Micheal Keaton definetly the best batman so far.
Jim Carrey did suit the Riddler character very well, even better than Robin Williams who was considered for the role up to the last minute.
Don't forget how dire The George Clooney effort was, the name escapes me now.
Uma Thurman was a great villianess, but Arnie totally ruined it, very hammy acting, he should stick to the terminator films.
