Those movies are so great. Probably stick with the G and PG options if there's a young kid in the mix (thinking of Princess Mononoke, which is PG-13, IIRC). The PG ones often have just the right amount of "safe-scary" elements that it absolutely grabs their attention. Great movies for grown-up/kid conversation-starters to boot, just due to the deep, rich, human themes they explore.
