Parents need to know that The Peanuts Movie is a sweetly nostalgic, mostly gentle take on the characters from the beloved comic strip/TV specials. Charlie Brown is still his same awkward, insecure self -- and Lucy is still rude and yells a lot -- but there's less of the insult language ("stupid," "blockhead") than in the classic specials, and there's no mistaking the movie's positive messages about being yourself, trying hard, and liking people for who they really are. Many characters have crushes on others (Charlie Brown blushes around the Little Red-Haired Girl, Sally calls Linus her "sweet babboo," Lucy flings herself at Schroeder, etc.), and you can expect aerial dogfights and peril in Snoopy's World War I flying ace fantasy sequences (which may feel even more intense in 3D), but it's nothing that most older preschoolers/younger grade schoolers won't be able to handle. Charlie Brown shakes his bottom briefly during a dance scene, and his clothes fall off as the result of one of his many comic pratfalls, but overall the movie has a slightly softer edge (and more upbeat tone) than some of the older specials.
