Yeah, The Rock was totally the best part of the movie. Cedric's monologue was pretty awesome, too.
It was too long, though, and a little slow in a lot of parts (mainly when the conversation was about Milian).
Definitely see Get Shorty before this if you haven't, though. There were a lot of small in-jokes (a billboard for Mr. Lovejoy, starring Tom Hanks, for example) that I (and no one else in the theater) laughed at.
