I took my son (aged 6) this weekend, as he loves the cartoon. I loved it, but I think it's geared more towards teenagers and older, as the plot involved alot of the love story and character development. The action scenes were well-done, just not enough to keep younger kids engaged.
Tobey Maguire is a really cutie-I think this role will make him a star. I hope he doesn't get pigeon-holed though, like Chris Reeves in Superman. I think he's a got alot of acting potential, provided he makes the right career choices. It will be interesting to see what he does next!
