Went to watch Speed Racer last night. It was an excellent time to shut off the brain, sit back, and just enjoy the visuals. I'll admit I'm not that much of a Speed Racer fanatic but I have seen the old cartoons and read some of the comics: the movie is pretty faithful to what I remember. And not only that: it really is a cartoon come to life. I'd watch it again just for the design sensibilities.
For those who haven't seen the cartoon, here's a montage of characters. Note the similarities with the actors in the movie.
