I was particularly interested in the age regression of Jeff Bridges. I didn't really like it. The age-regressed Jeff Bridges looked like the characters in Beowolf. The mouth just wasn't right. Also, I don't think they changed Bridges's voice, so there was a mismatch between the way he looked and the way he sounded.
Ross had a lot more to say about the movie than I did. He was a lot more critical. I didn't really even notice the things that bothered him. I think I agree with Ross though that the first movie was better.
