This is the classical Thriller-Horror movie of a group of characters trapped in a place surrounded by things/people that can kill them. In this case there is a monster outside, but clearly this is no "Assault on Precinct 13". The movie is mildly entertaining. The characters are not very well written, but they are not horrible either. The special effects are fine; not good not bad. And I would have enjoyed it much more if it wasn't because of the stupid modern resource of the shaky camera and electric editing, that makes the end result just barely bearable.
