Overall the martial arts action was fantastic. However I personally think that there was too much gore and this is coming from a person that loves a good gory movie.
For some unknown reason the director or whoever felt that blood or body parts needed to be flying all over the place every minute or so. This was very detracting from the overall movie itself.
I also feel that the ending was rushed. I dont mean with the cavalry coming to the rescue I think that was an excellent touch. I mean where the master was kicking the s**t out of his pupil and all of a sudden the student was better than the master?
