Another comedy that doesn't quite get going. Diaz plays the lazy, bitchy teacher very well, its just that she doesn't do anything particularly bad. Well nothing any worse than any of my teachers did anyway! She plays the don't care role very well against the ditsy anally retentive rival teacher, and tries to take the teacher bonus for her own boob job. She hates the gym teacher (but who doesn't), but falls predictably for the rich cute teacher played by Timberlake. However in yet again predictable rom-com territory you can probably guess what ends up happening. A few chuckles, but far from great.
