Bad: some of the effects (knife cutting levitated pear was crap, assassin getting out of buggy was crap). All of the screenplay. All of it. Too long, way too long. The direction sucked, too. The actors were obviously instructed to deliver their lines as though it was Shakespeare, and there are stupid things like two seconds of character shot where the only word is "hmm". BOR-FUCKING-ING.
Summary: Lucas thinks he's Speilberg, but he isn't even South Park. The only upside is that an entire generation of filmmakers will get their start because they walked out of the movie theatre swearing and saying "I could do better than that!"
