Good "self-confidence building" movie for teen girls - "AquaMarine".

I told my wife it was a "pre-chick flick". You have to put yourself in the mindset to watch it (not much different than "Lady and the Tramp" mindset), but it does give a very positive message and is targeted at a profoundly insecure time in a girl's life. They even touch on issues of insecurity about boob development, but in a funny way. It has a really positive message and I think most girls would enjoy it, and well, most boys probably too because there's the HINT of nudity (nothing visible). Boys would learn from it as well. It's sort of silly at times, but also very serious. If you've got kids in the 4th - 9th grade range, I think they would enjoy it.
