take your video camera and turn out all the lights in your house and film people running around with flashlights for an hour and a half and you have got the basic idea of what this film looks like. it is very irritating to watch this kind of movie. to be fair and there are scenes of daylight at the very beginning and very end of the movie. i like scary movies and creature features but this one just do not do a thing for me. so sorry. i really tried to like it. there do not seem to be much of a plot other than we have got to find a way out of here. didn not learn too much about any of the characters so it do not matter if we lost one or two along the way. this isn not the worst movie in the world. open water holds that title for now.
