The movie isn't Alice in Wonderland as we know it. The story is suppose to be that alice goes back to wonderland but she doesn't remember it and somethign has happened to wonderland.
Off she runs, following a white rabbit into a hole and ending up in Wonderland, a place she visited 10 years before yet doesn't remember.
So I dunno, not so much aimed at young kids I don't think more of your tweens and teens.
