As far as the fighting is concerned, I thought that this one was a little unimpressive. It's pretty slow, overall. I'd really only recommend it to big fans of the first two. There are some good bits of humor and we see some actual romance between Wong Fei-Hung and Aunt 13, but I don't think that that sort of thing is the main reason we watch this sort of movie. And even if it were, there's just too little of it.
I really think that Jet Li's talents are wasted when you try to use goofy camera angles to make it look like he's doing superhuman feats. The man is practically superhuman already. I think you're better off showing off the amazing things that he can do rather than focusing on trying to make him look like a cartoon. I'm sure that his work in the movie was very demanding, but it just didn't come off as too impressive on the screen in my opinion.
And way too much lion dancing.
