I saw Kung Pow back when it came out. It was alright. Meh.
Kung Fu Hustle was practically made entirely by Stephen Chow, wrote and directed by him and such. He's also the main character. Most people don't know who Stephen Chow is, but reguardless he is a god of a film maker in China. Trust me, this is nothing like whatever Kung Pow was about. Although it is a good comedy, it does well as an actual kung fu movie, and in some scenes maintains its ability to be a love story. I don't think anyone will be dissapointed by this one.
(Secretly: The part where he gets pee'd on was alittle wierd, esspecially when they showed it again)
I'm not sure if someone was lost in the subtitle translation, or if in the original language (whichever one it is, as "Chinese" isn't really a language) they were really so clearly defined as the "Evil Team".
I also found it funny that they thought "American drugs" gave them superpowers. Seriously, drugged up Americans have small penes and hang around their porch laughing at everyday things.
