I know this is really sad, but the only reason I watched this movie on TBS one night was because Adam Pascal from Rent had a small part in it (Theo, the guy who kciked Dewy out of the band). I didn't expect much, considering Jack Black was playing the lead. But boy, was I wrong. This was a hilarious, rock 'n' roll film. The kids are great musicians, especially Zack (Zack Attack) the guitarist. Tamika (Turkey Sub), Alicia (Braceface), and Marta (Blondie) are great singers. Miranda Cosgrove plays her very annoying charcter, Summer Hathaway, perfectly. And Joan Cusack was so funny as Ms. Mullins, especially during the bar scene. I am surprised this movie is not PG, because the humor is not as bad as a lot of PG movies, and there's only a couple times they curse. Little Giants got away with a PG, why couldn't this? Overall, a very good movie when you feel like you need a good laugh.
