Saw it today, I agree it wasn't highbrow entertainment but as far as popcorn crunchers go it was great, lots of excitement, car chases and I love that guy who plays Riley the sidekick, he has some great one liners.
I didn't think it was quite as good as the first - the bad guy wasn't quite as evil and the mystery wasn't quite as compelling - but the performances were all good and they all clearly enjoyed making it. And I'm really annoyed that we have to wait for page 47!!!
