It's a shame MST3K died before they could do this stinker.
I was just exposed to Kung Pow this Saturday, thanks to my brother's co-worker who lent my brother (or is that "forced my brother to borrow"?) the DVD of this flick. We watched the movie five times in two days.
I'll be quite honest; this movie simply is not for everybody. But if, like me, you grew up on badly-dubbed Hong Kong martial-arts flicks, you will LOVE this send-up of the genre. The action is top-notch (though that's more Jimmy Wang Yu's triumph than Steve Odenkirk's), the dialogue and voices are roll-on-the-floor-laughing funny, and the cliches that have haunted all aspects of action movie history, from '70s "chop-saki" flicks to modern big-budget explosionfests, are brilliantly mocked.
On the technical side, you have to marvel at how seamlessly blended together this movie was. Despite the fact that Odenkirk, Lee, and the rest of the modern cast are separated from the original "Tiger and Crane Fists" cast by 25 years and half a world, they actually convincingly interact with each other. You could actually believe that they're all there, on the same sets, acting out each scene like any other movie.
Again, this isn't for everybody, and if you aren't a fan of Hong Kong action flicks, you will not get most of the gags. But if you are, this movie is pure comedy gold.
Recommendation to AVOID.
