Wow was it good!
I was willing to take the kids to see P2, but I was not optimistic that it would even be as good as P1, which I thought was cutesy/good but not particularly appealing to adults. But I actually think seeing P2 was about the best experience I've ever had watching a movie (like Schindler's List, but in the exact opposite way). P2 is fun, action-packed, heart-warming, has a good message, clean, easy to follow, well-animated, hilarious, and well-acted. People giving this movie fewer than 4 stars seem to be doing so because their individual children were traumatized, not because of the movie itself. I reckon if you have a hypersensitive child that really really wants to see this movie, you have a choice to make, but I doubt too many kids will be scarred for life from watching P2. I'd say if your kid can handle the traumatic scenes in the movie Up, your kid can handle P2.
