Honestly, I have no clue why I love this movie so much. It seems like every time I am looking for something to get me on edge I automatically think of this movie. The movie is set in just one building with a few scenes else where which therefore, makes it easy to follow along. A well made movie does not only effect a person's emotions while they are watching the movie, but also effects them after too. The fact is that this movie has a way of making people want to pray afterwards "just for good measures" people (meaning me and friends) would say. Literally, when the movie got to the point where the detective was telling the lady and man to "take responsibility" I started confessing to all the bad things that I could remember; which lead to a very embarrassing moment where my friends were looking at me like I went crazy. Anyways, overall most memorable movie that you would love to watch again.
