Some of Jackie's best fight scenes ever are in this one. Nobody mentioned the one near the end where he's attacked by 3 guys with spears / machetes (you'll see what I mean). The attacks come one at a time, and then all in sequence. The cuts show that there are very few breaks in the action, lots of continuous fighting. Amazing nobody got seriously injured or even killed during the filming.
Another scene of note that everyone talks about is the chopstick scene. But how about the fight against the guy with the two swords? Yet another death defying feat of timing, reflexes and luck.
If you don't enjoy HK humour then don't watch it. But the fight scenes are among the best ever. For those complaining about the dubbing, relax - even the Cantonese version suffers from very poor dubbing. I think it was just the studios at the time trying to save money.
