This is the Batman I've longed to see after years of reading The Long Halloween, Dark Victory, The Dark Knight Returns and other titles of the Batman. The movie has a great blend of masterful acting (not a bad performance in the bunch), a solid crime-drama script, a subtle yet fully effective score, and great shots - both in the action and narrative scenes. I agree - not the best movie ever made, but it's the best I've seen this year. It's also a bit too dark for younger kids/pre-teens too - I'd recommend taking older teens at the minimum, perhaps older than 13 despite the rating.
Okay - PURE camp, but if you didn't expect that from the trailers you're blind! This movie was totally fun - my kids loved the racing, and so did both of us. There's some cool effects, and it's completely larger than life and full of shocking colors - and a corny, dramatic story line. But see this on the big screen - I suspect some of it's bang will disapate on a TV, even a 42" HD TV at home.
