But
'12 and Holding'
is also a good movie. However, not one to watch with your young friend, it's a very realistic, down to earth movie about 4 (really 3) 12 year olds. They discover swearing and do it quite often (I wonder the the actor's parents where thinking, hee hee)

One girl, and you can guess what that one is about. (gross)
A boy, dealing with a loss of a loved one.
And an overweight boy who decided to fight his weight issues.

However the movie is, like I said, a very serious tune to it, but it's great non the less and would highly recommend it.
