I watched this movie and I loved it! I thought Kat was a smart, strong-willed, good role model. Her only drawback is how confrontational she can be. Also she lifts her shirt and shows off her chest to a teach to get a classmate out of detention, so beware, although no nudity is seen. Bianca, Kat's younger sister isn't a bad character, she just wants so much to be one of the shallow, vapid 'popular' girls, that she can sometimes come off as weak. There's some bad language but most children these days hear worse just walking through the halls of school. The drinking in the movie and the making fun of the less popular students are the major drawbacks, but even these things can't subtract from this great movie!
