Massawyrm at AICN makes some really good points about the whole "kid's film" debate: http://www.aintitcool.com/node/37951

"Kids Movies are films that are meant ENTIRELY for children. That is they either do not take the entertainment of adults into account or completely fail to entertain them when they try. You can spot these a mile away. They contain goofy characters falling down, making biological/caka/doodoo/peepee/fart jokes, are accentuated with tons of sound effects up to and including slide whistles, and are a veritable rainbow of colors and shapes. Their very intent is to grab a hold of the miniscule attention spans of young children and keep them focused on the screen for 90 minutes straight. They are cheap, easy to make and entirely disposable.

A Children’s Film on the other hand strives to entertain not just those same children, but their families that accompanied them as well. They are elegantly told stories that hit all the same kinds of notes that the story of a Kids Movie would, but often have deeper meanings that mean something completely different to adults. They are films that grow up with you and that you can carry to adulthood and love just the same, if not more, than you did when you were a child. Films like The Iron Giant, The Dark Crystal, The Harry Potter films, virtually everything by Pixar and of course my favorite movie this year (not the best, but the one I’ve watched the most and will no doubt continue to watch again and again) Kung Fu Panda...........

.............But lets step back for a moment. Tell me something. In what universe do you live that the charred, smoldering remains of a character’s aunt and uncle constitute the makings of a kids movie?"
