I just saw this movie tonight, and it was awesome.
The only beef I have with it is when body parts get cut off, they bleed like woah. Maybe that is something to do with kung-fu movies or something, but I didn't like it.
Other than that, everything just flowed so well. Uma was excellent in this movie, her acting to the fight scenes. It never went to slow, nor did it go to fast. Like I said, everything just flowed together so well.
Best movie I have seen all year. This deserves an Oscar, though I doubt it will get one.
