Let me begin by saying I was reluctant to let any of our kids see this movie, but my husband won that argument. Their ages are 11, 10, 8, and 4 (yes, 4) and they all went to see it tonight. It was almost non-stop violence and action but for the most part it never seemed gruesome or unnecessary. I glanced over at our 4 year old about a hundred times during the movie to make sure he wasn't traumatized and not once did I see him get upset. There's a scene in Monster's Inc. that he is terrified of, by the way. All in all, I thought it was appropriate for any kids who don't get scared too easily and who have an interest in "fantasy/sci fi plots." There were a few offensive words throughout, but unless you see a G movie, curse words of some sort are unavoidable. All in all it was a better movie than I anticipated, less scary than I had imagined, and less sexual content and language than the official review led on. Our family of six all give it 5 stars!
