If your eleven year old daughter wants to see it, let her. There's very mild sexual references but nothing major and most tween girls absolutely love this movie. Not very deep or educational, but a good teen chick-flick.
There is so much good stuff in this movie that I allow my 6-yr old daughter to watch it (the sexual references go over her head). However, there is one blatantly sexual, stripper-like audition scene that I fast-forward through. For kids who DO get the sex-talk, I'd recommend parents see it first.
The movie is mostly bubblegum cheerleader sex with teens.
It's funny in some areas, but just disgusting in others. If you insist on seeing it, make sure you discuss with your teen about healthy sexuality.
This film show cultural appropriation really well with out being preachy but simple and entertaining enough for teens to understand. Kristen Durst is a real good strong female role model. There is some strong language and they refer to gay people using words that are offensive by today standards (you should tell your kid this). There is also sexual talk (no acts shown) that may be inappropriate for the younger ones, use your judgement. Definitely show your kid this one, at some point.
A movie I enjoyed from my younger days. I watched it with my almost 12 year old and there were a couple of times we had to pause and discuss. Mainly there was a gay character who was shown in a positive light but was still referenced to as a 'fag'. There is sexuality because hey, they are cheerleaders and like skimpy clothing and there some bikini car washing scenes. There is the pervert cheerleader boy, who in today's climate would be dragged through court for the way he lifts cheerleader girls, but I think most kids will miss that. The younger audience should probably watch with some guidance.
