I had really low expectations when I started watching this movie, and I was pleasantly surprised. It was campy, and fun. It made me smile in several places. The special effects were very cool.
What I found most impressive was the compositing and editing of the different scenes. They used this device a few times that I really enjoyed. to cut from one scene to another, they would "wipe" a talking head across the screen. It had the effect of keeping the action nonstop while transitioning to a different point of view.
Not the best movie in the world; but it was still enjoyable.
