A lot of people seem down on Batman Forever. Granted, I haven't seen it since I was a kid, but I loved it then. I still love the 1989 Batman, but I'm not one of those who thinks that only Keaton is Batman and only Nicholson is Joker. Batman returns was ok. I had seen it once when I was little, and then again this year. I thought the film's main saving grace was Michell Pfieffer's Catwoman. Certainly added a layer of depth to the character. I found the Penguin, however, to be an uninteresting and unappealing villain. The film might have been better without him. Batman Forever I enjoyed (Nicole Kidman was probably my first movie star crush, and Batman Forever is solely responsible for that). Batman & Robin is pure crap though. Not really even funny to watch.
Batman Begins I honestly didn't love. I thought it was good, but not great. I do look forward to seeing the Dark Knight though.
