Terrible! The plot was thin and silly - rule by martial arts? The characters were lacking in charisma so that I did not care who won - in fact I was rooting for the "baddies"!
There was a sad attempt to make it look "arty" with weird camera angles and split screens, but this was just annoying. The "martial arts" were mostly slowed down or shot from odd pov's, almost certainly because the actors were no experts, which is understandable but wasn't very realistic.
Dominic Monaghan, who was probably the biggest name in the film, was a craven turncoat and a dreadful waste of talent. He spent most of his time fighting girls and losing or just betraying people for no well-established reasons!
