Fine for teens but not for younger children.
Having read the parents & kids reviews on this website for this movie, I was in a real dilemma as to whether to take my boys, ages 11 & 14. I really, really wanted to see this movie as the trailer looked amazing but the animal violence worried me. Turns out my boys weren't very interested in seeing it anyway, so I took myself off to see Life of Pi in 3D with a little trepidation (I'm a bit squeamish with violence). Well, I thought the movie was amazing, beautiful and very thought-provoking. And I really regret that my boys didn't see the movie, they would have loved it. My 14 yr old was definitely mature enough to watch it and my 11 yr old is not a highly sensitive animal lover and does like a bit of a scary movie, so he would have been fine with this. I would not recommend it for children much younger though, the animals attacking each other would be quite scary for most kids (though you don't really see anything too unpleasant, it is more the fright of knowing/seeing one animal is trying to kill another). As my 14 yr old said (when I told him about the movie), it's nothing worse than what you would see in a wildlife doco.
