If you're after a review of the full version of Bioshock you can go to gamearena.com.au and they've got a review of the full game. Apparently they weren't allowed to post the review until the game was on sale, but since Toys R' Us started selling it early, they decided to post a review early.
Let me suggest to anyone who is really interested in this game not to read the review. A few spoilers and one of them is criminal. If you played the demo and listened to Diane McClintocks journal, this review makes it fairly obvious what started happening while she was making it.
They give it 5 out of 5 stars and say it's an awesome game.
