I personally love the movie and I've seen it three times.
I don't really understand why people don't like shakey cam. I feel that it adds to the ambience. It doesn't make me nauseous or anything, I can easily keep up with what's going on. Then again, I'm not old, or have poor reflexes.
I thought the ending was wonderful, and unlike some people I know, I don't think it set up for a sequel in anyway. I hope they don't make a sequel.
I saw it in a theater that was recently built near here. They use JBL for the audio and have excellent projectors and screens. Plus, the seats are amazing. Very comfortable, large, and the back goes up past your head. They also lean back very far.
And it only costs $5!!! Screw Showcase, they charge $10.00 for a crappy theater.
