The movie is solid and disturbing at the same time. (This is going to sound like an imdb review) But this movie made me lose faith in humanity. There is no way people can be this naive and stupid to do anything like this. It took one maintenance guy to realize that the guy on the phone is LYING. Think about that ONE GUY, whilst the manager was like "I wAs juSt DoIng was I wAs ToLd".
