There are scenes in the classic early Disney movies that can be quite scary for little ones. Maleficent turning into a big, nasty, purple dragon in
Cinderella made an impression on me, and I wasn't little at the time. The whole evil stepmother trope might not be quite so benign either if you're a child of divorce and your Dad just remarried. I don't have personal experience with that, but there's something about Snow White's stepmom and the big, red, juicy, poisoned apple that still gives me the creeps. Don't even get me started on the
Night on Bald Mountain sequence in
Fantasia. Don't get me wrong: I love these movies, and they're artistically superior to the Pixar films in my opinion, but there are parts when a trip to the concession stand with the very young ones might be a good idea.
