I tried rewatching this a while back, ended up pausing after Ivy breaks Freeze out of Arkham, and then just never bothered to finish it.
The only aspect I appreciate more now (about both this movie and Forever) is the production design and art style. As garish as it is, it's wonderful how it actually looks like a comic book, and very specifically like the Batman comics of the 90s. Norm Breyfogle and Kelley Jones were clearly massive influences and I liked that.
Otherwise, it's dull. The actors are clearly more in on the joke than most people give it credit for, but it's a very one-note joke. You've seen everything the film has to offer within the first 20 minutes. The most notable point after that is the Coolio cameo. The rest is just boring. Clooney is boring, Batgirl is boring, Robin is somehow even more boring than he was in Forever, Ivy vamping it up is boring. Even Mr Freeze's cheese eventually ends up boring. There are far better so-bad-its-good films out there.
