First of all, there's not much kung fu in this movie. It's just a guy in an ape suit and goofy comedy. Don't get me wrong, I was expecting an ape suit and something silly... but... it was too silly, and it was not half the action movie I hoped for.
It could have been a fun movie but it was too desperately trying to be funny. Over-acting, spoof characters, cartoony sound effects and cheesy comedic music...those are all things that make me squirm and want to look anywhere else than on the screen. I tried to keep focused but failed, and during the movie I read newspaper, browsed record shop, made more tea to stay awake, planned how to build shelves for my movies, browsed ratings I have given to other movies, thought other annoying movies I'd rather be watching instead, and some boring chores on my to-do list...then I always quickly came back for the movie but it felt like a difficult task to finish.
There's not much plot, and the whole thing about the movie is that if you like the particular overtly silly tone of it, then you like it... but I didn't. If you happen to like slapstick and 70s' camp a lot, then you'll probably get more out of it.
