This is the kind of movie that I think a lot of people will hate. It is like an experimental moral fable put to film. It did have one really good twist, and generated some effective suspense. However, the movie feels claustrophobic with much of it filmed in a tiny elevator, which gets tiring after awhile. And too much blood in the movie too. I'm a little torn on my feelings about it, it wasn't all that entertaining to watch, but did keep my interest. Some of the acting was good, but at the same time there is some lousy acting going on too. Like I said, this movie is pretty evenly balanced between pro and con. I tend to give it the benefit because it is a different type of movie than most of the mainstream stuff out there.
