I agree with another reviewer on this movie. This really is all over the place. The director seems to have no direction ironically enough. It can't seem to decide what genre it wants to be, a horror, a martial arts or a dystopian post apocalypse but fails really in all areas. There is a fair amount of illogic in it which makes it very disjointed and nonsensical. It was empathized in the first part of the movie that the storm clouds in the sky were strange, alluding to this being the cause of the oncoming zombie outbreak but this was a pointless exercise as it had nothing to do with it. Also the dialogue kept being intertwined between English and Mandarin for no reason at all. Conversations would take place where both languages were mashed together when they were all obviously native Asians and there was no need to speak dual languages in the same conversation. Why was there a car half way up a high-rise and why did they drive it along a corridor and nose dive it off the building? These were all just plain daft scenarios that should never have been put into the movie. The second part of the movie was kind of tacked on and didn't flow at all. It's almost as if the director just ran too short on the first half so padded it out with this bullsh*t section. I hardly think a timid school teacher from the first part of the film would be a gangland boss in the second half. This was a totally preposterous idea and just spoilt the movie. I just think the director wanted to cram too many ideas into the movie or wanted to make many movies but only had a budget for one. Either way it didn't work and what could have been a perfectly adequate zombie-fest in a block of flats turned out to be a confused, illogical and shabby mish-mash.
