This was pleasantly interesting. I was hesitant at first, given the plot: A movie about making a movie about a movie. But knowing it had Jack Black and Paul Rudd, I knew it would be entertaining. The Ice Cube cameo was great, the J. Lo one, not at all - I have no idea why society ever worshipped her. Her music and movies suckked. I digress. I give this 8/10 smiles.
