Let me begin with the positive. The actors were amazing and the movie had me on the edge of my seat for the first 30-40 minutes. It was hauntingly scary, because I live in Chicago. The movie gives you a realistic view of "What if". The only problem I had was the ending and I'm not sure if thats a problem or not because it left me thinking. I do hope if this scenario was to happen decesions would be made swiftly!!
