Go Goku!
Surprisingly non-cheesy! All the elements of the anime were there, but with enough reference to the "real" world to make it seem relevant. They didn't try to overwhelm the story by introducing too many characters -- there was one bad guy (Spike from Buffy the Vampire Slayer, actually) and his one henchwoman. The hero had some allies of course, and a mentor (Chow Yun Fat, awesome in Replacement Killers).
Full stop, my favorite scene is the one where he doesn't fight the high school bullies at a party.
