I liked it myself. It was far better than I'd thought it would be. I liked the Journey To The West references with the Monkey King and the magic staff. It was cool to think that technically this story heavily coincided with Dragonball; The Monkey King being Goku, and the staff being the Power Pole.
[spoil=Um...Movie Spoiler?]I especially liked seeing Jason kick the ass of the gun-toting thug who made him help rob the pawn shop. Did anyone else realize as soon as they saw him that the pawn shop owner was Jackie?[/spoil]
I tell you, movies with this kind of fighting make me wonder if ANYONE in the world is capable of fighting as fast or as elegantly as you see here. I imagine the answer is no, myself. I don't care how skilled you are at martial arts, eventually one of the dudes with the swords is going to get lucky and slice your head off.
