Roger Corman is a master of the B-Movie on the cheap. Considering Death Race 2000 was filmed almost 35 years ago, it's a funny movie.
I found the new version to be just too Hollywood, not enough independent thought toward a good movie, more toward making that big profit by big explosions and lots and lots of bullets. That said there were more then a few enjoyable spots in the film. It wasn't a bad film by far, just the were things which could've made it a great film.
