I had to watch this movie for a class, and it was quite good. I love how it managed to string together a bunch of whiny, borderline bratty kids and make them all sympathetic... not to mention, the characterization was really strong.
The best part, though, was the screen at the very end. :) I love how the entire movie is about them desperately trying to win a championship, they have heartbreaking losses and come just short, and then we find out the year after... they win the championship, undefeated. Nice touch.
