It's true that the story didn't break any new ground, but the effects were amazing. The IMAX 3-D itself was worth the price of admission. I've never seen a movie like it. The 2 hours and 40 minutes went by very quickly. Even though it's rated PG-13, I don't recall much that would be inappropriate for a kid. There's a little bit of language (hardly any that I remember) and, of course, violence from the battle scenes, but nothing horrific. I'm a pretty conservative parent and I'd let my kids see it. They'd be amazed by the visual effects.
