Coming from a fan of "Mystery Science Theater" and B-movies like "Plan 9 From Outer Space", I have to say "King Kung Fu" is one to see if you're in the right mood.
If you think the idea of a guy running around in a cheap gorilla costume beating people up sounds funny, then you're on the right track.
It certainly has its moments that made me laugh my ass off.
Why include a John Wayne impersonator, I have no idea, but it's hilarious! He's my favorite character and his impression is spot on, yet hysterically bad at the same time.
It's not a high class movie by any means. It's slapstick humor. I've seen it criticzed for its cheap gorilla suit and bad acting. It seems some reviews actually take it seriously and don't realize it's a comedy.
But the jokes range from clever like "I'm the karater and he's the karate" to just plain dumb "I gotta make like a banana and split." But when the jokes are bad, they're funny BECAUSE they're so bad. And that's what to expect from a movie like this.
If you like cheesy, out of control, "So bad it's good" movies, then give it a watch and you're sure to have a few good laughs.
