The film was entertaining overall. Totally sufficient for a light, fun night out. It will give you and your friends plenty to discuss afterwards.
The plot was unfocused, but not difficult to follow. The twist at the end was somehow both surprising and predictable at the same time.
For the most part, the characters were bland and the audience did not get to know them well. That might be due, at least in part, to the mediocre acting.
Upon further reflection, I think that the movie was supposed to be a comedy moreso than a horror movie. I wasn't scared or shocked at any point during the film, but I did find the cheesiness to be funny.
The best part was by far the cinematography - excellent lighting and camera work.
