Oh, let's add to that the kid in the film, Russell, is chased by a terrifying villain with a SHOTGUN who repeatedly shoots at him, ties him to a chair and shoves him off a blimp in a quite obvious attempt to murder a child, and dies a graphic and horrible death as we watch his face as he plummets to the earth.
OH NO!! VIOLENT SITUATIONS IN A DISNEY FILM!! I guess I'd rather watch...
Snow White: when the witch tells a hunter to kill Snow White and bring her heart back in a box
Pinocchio: when bad kids are kidnapped, turned into donkeys, and shipped off to salt mines
Finding Nemo: when Nemo's mother and siblings are eaten by a barracuda before the opening credits
The Little Mermaid: where people who don't live up to their bargains with Ursula are turned into squids
Beauty & the Beast: with a villian who also "dies a graphic and horrible death as we watch his face as he plummets to the earth"
Peter Pan: where children are rounded up by pirates and nearly forced to walk off a plank where a crocodile awaits
Lilo & Stitch: featuring a child whose parents were killed in a car crash
The Incredibles: featuring supervillians who try to wipe out super-kids
Tarzan: with a villian who falls to his death being strangled by vines
So thank goodness the other films don't include witches, dragons, evil stepmothers, evil stepsisters, sinister villians and creatures to bring on chaos and peril for the diaper crowd.
UP is rated PG. It's not for the "diaper crowd". And it certainly wasn't made just for kids.
