As others have noted, this is a love it or hate it film. If you're watching with any expectations then you'll likely be disappointed. If you really want a cheeseburger, but you're surrounded by sushi places, then it hardly matters if the sushi talks and the wait staff are naked and the condiment bottles all have drugs hidden inside -you're just not going to enjoy yourself.
On the other hand, if you're bored and hungry and can't decide between a sports bar run by drunk chimpanzees where every other TV is either playing an episode of Night Court or a live tennis match between dead people, and a brothel that only serves sushi on the naked bodies of giggling mental patients, then you'll probably have a blast. If hearing every word of clichéd dialog is more important than wondering why you can't hear any of it, then you'll be a sad panda.
Overall, this movie was a rewarding exercise in surreal dark comedy. It subverts expectations, and in many cases abuses them outright. Is it silly? You bet. Is it bad? No, not if you understand what it had set out to accomplish. Is it funny? I certainly thought so. The ending pretty well ties it all together. It's less of a mess than Rubber, but enough of a mess to illustrate WHY it was intended to be such a mess. If the cast of Seinfeld were dosed with acid and then set loose on the set of a B-movie crime drama, it would probably make for lousy television, but the guy with the boom mic would be laughing his a** off, and so would I.
