I really liked this movie but I wanted so much more from the CGI. First of all I suspect the story was based on the MacPherson video tapes which I am a big fan of. Second, most of the film took place on an army base which caught me off guard and peaked my interest, great surprise. And third, this movie kept me thinking, what's next, what now? All the way up to the end. On the negative side I was preoccupied with the cheap sets and the so so monster costumes. Also, I kept having to push my volume button up and down throughout the film. At one point there was no sound at all and I thought that my TV was on the blink. When I rented it I expected a regular movie so it was a little surprising how cheaply done this was. But the story was so good and disconcerting that I was gripped from beginning to end. I also liked the tall, skinny blond actor because I didn't know what to expect from him and the lead actress was great. What was up with her friend though? Is that her real voice? I will watch this film again with my wife because of the MacPherson connection and the fine conclusion which really caught me by surprise. Over all, very positive.
