For the record, people love this movie. It was nominated for an Oscar (then again, so was Titanic, so take that with a grain of salt), it's based on an acclaimed book and was made by the same director of an another beloved movie, The Nightmare Before Christmas.
All of that is well and good - the problem is people have started to equate animated movies with kids movies and that's not always the case. Many adults will love this film. Many teenagers too and I'm sure there are a lot of young kids who will dig it as well. But watch it for yourself first to decide whether your child will be bothered by things like losing your parents, having buttons sewn into your eyes, creepy houses, ghosts, etc.
Now I know what you're thinking - "you're a parent, it's your responsibility to pre-screen everything your child is exposed to." To which I say two things...
1) What about the time I need for other, equally important things like checking my fantasy baseball team and reading Lost recaps?
2) Bite me.
