Shock Rating
G
This is a Disney film, folks. If we could give this movie a rating that meant "less scandalous than G," we would.
All of the violence is pretty tame, and there's no blood—even where common sense tells you there should be blood. And you can forget about sex: Simba and Nala don't even kiss. They nuzzle. Once. Maybe twice.
Basically, you could show this movie to a newborn, and the kid would still turn out okay.
