I am no big kung-fu movie fan, but this really doesn't matter, as this is not a kung-fu movie -- at least not in the sense that "Hero" or "The Tiger and the Dragon" were. This movie is pure joy, and the kung-fu setting is merely incidental. I watched this movie on the plane, and it was so much fun that I think I kept the other people in my row awake because I was laughing aloud the whole time. The gags are very well made. The whole tone of the film is very tongue in cheek, but absolutely not pretentious. And although the humor is unpretentious and very visual, it is by no means slapstick. There are clear good-natured references to other recent movies, but this movie is not a parody or a satire. In fact, I find it hard to classify this movie. It is neither high-brow nor low-brow. It is neither Steve Martin nor Leslie Nielsen. This is John Candy and Steve Martin together, as in "Planes, Trains and Automobiles", with action scenes directed by James Cameron! It is one of the funniest action movies I have ever watched! I highly recommend it to good-natured, fun-loving people. I would watch it again over and over. I believe this is going to become a cult movie in the future. It is utterly original, intelligent and lovingly made.
