The movie has a bad habit of violently swapping from serious to comical without any notice. Oftentimes in the same scene you have jokes mixed with soap opera drama. What is really infuriating is that, if done in one style or the other it would have been a pretty good movie, but the strange shuffling of the two made parts of the movie really feel awkward.

Some of the characters too couldn't seem to find a groove; especially the second girl, Lily, who goes from terrified, to suspiciously guilty, to bitchy, and often all in the same couple of minutes. It was probably done to make you unsure who the killer is, and it almost works, but it was done too over the top.

I had hoped for something better from Herman Yau, the guy who gave us the gore feast "Ebola Syndrome", but this doesn't seem to be his cup of bloody tea. There are some good gore moments, but the whole mystery movie isn't something that is done well, with maniac bipolar mood swings every couple of seconds. There is a pretty good movie in there--the last twenty minutes or so really helped bring me around for this movie with the running, falling, door mauling, and a decent conclusion--but you have to be able to put up with some off-putting moments to get there.
