Yeah, it still has some dark moments, a li’l violence, the word “Hell” being used, (“Sleeping Beauty” got away with it too) and some surprising subject matter not normally in Disney movies.
Such as villain Judge Frollo’s questionable morals, and religious-hypocracy. Though, at least, it still treats religion/religious folk fairly, (unlike alot of media nowadays) as the preist calls out Frollo on his B.S., (so there’s some good religious characters) and the Notra Dom church itself is sort’ve treated as an important symbolic character/landmark too, and as a safe haven. Not to mention, Frollo’s ironic demise complete with Bible quote was epic.
Still, it has some standard silly/comical characters, & moments (“Oh, look a mime!”) and musical Disney fair to keep it from being too gritty, and grim. The best Disney movies oftentimes have the light & dark content balanced well.
