Batman and Robin. I KNOW it's cheesy as hell but I was a kid and I loved it. I loved the aesthetic of Gotham but found the previous Batman villains too scary (Penguin, Two Face) but Mr Freeze and Poison Ivy weren't scary at all. It was a romp!
It's Batman Forever for me. It was my favorite of the Batman films until dark knight came out but everyone else I know hates it. I think maybe I'm just a big Jim Carrey fan and he elevated the movie for me.
It want's to be cheesy and not serious like the newer Batman movies. It's like the series with Adam West. People not liking it are expecting something other.
Joel Schumacher had the right idea, but should not have been given final edit. He was Hollywood's last expressionist. He updated Burton's inky-black Gotham with the garish colors of 90s comic books. It's still deep contrast against rough concrete. The low-angle lighting on every enormous statue just happens to be neon.
But the man could not hit the right level of camp. It wasn't completely silly, like "some days you just can't get rid of a bomb" Batman. It wasn't an internally-serious ridiculous reality like The Animated Series. It wanted pathos with Alfred and Mrs. Freeze, while still having... a Bat Credit Card.
