Planet Terror is one of the cheesiest movies I've seen recently, but the fact that it is made that way on purpose makes it funny and actually very enjoyable at times.
The dialogues are phony and way out, the characters are ridiculously exaggerated and nothing makes sense in the movie. But if you're willing to let yourself go and have a good time watching a movie that doesn't take itself seriously at all, you may actually find it funny and entertaining.
It's also a plus to have great actors like Bruce Willis and Josh Brolin making fun of themselves in a movie where nothing is as disgusting and bad as it could be because it's so fake.
