There's a very definite crowd that will hate this movie, this rant isn't for them. Kung Pow! will most likely be loved by any loyal fan of Mystery Science Theater 3000. It's also great for fans of Monty Python, Dumb and Dumber, Ace Ventura, etc. Basically, it's stupid comedy. I'm talking, /really/ stupid comedy. That's why it's so funny, and some people just won't get this.
So, what's Kung Pow! all about? Well, Writer/Director/Lead Actor Steve Oedekerk basically takes an old, unknown, laughably bad 70's kung fu movie and one ups MST3K by not only making fun of it, but throwing out the dialogue and sound. They redubbed the entire thing. They digitally added several characters, including the main character, into the film. Everything is then mercilessly hacked and ducted taped together to form one hilarious story.
The jokes are certainly hit and miss, but that's to be expected in this type of film. More or less, it's a great comedy with a lot of action. The story, although very fragmented, is rather entertaining as well. It does manage to keep a sense of continuality though all the random fun. The end of the film, although unusual, will be well known to any anime fan. Suffice to say it's almost like watching Kung Pow! 2 in 30 seconds. It's very entertaining.
So what else do you need to know? Go rent it! Keep an eye out for WimpLo, a great MST3K style humiliated character. "We purposely trained him /wrong/, as a joke!" The cow scene isn't nearly as lame as it seems in the previews. The cow itself is actually quite well modeled, and animates smoothly. It's somewhere around 5x-10x the detail of the Black & White cow, if that helps anyone. Have fun, and keep the scoffing movie critics out of the room while watching. Threaten them using various WimpLo quotes, that'll keep them away for awhile.
