I'm also very impressed. I had heard rumors that Disney was going to go the whole Christian (Passion of the Christ) route when marketing the flick, which turned me off a bit.
While they still might go for that market (let's face it, they'd be stupid not to), it's nice to see that they're going for the SF/Fantasy crowd first. It looks like it's going to be cool adaptation - gets me more excited than HHGG did.
