Song of the South. Yes Splash Mountain is themed after it but how many kids know where those characters came from?
Great shout. It's sad it's been so repressed.
I'm not really sure how the world sees the Hunchback of Notre Dame, but you certainly don't hear much about it. Compared to The Lion King for example, which was from the same era, but is lauded constantly. The Hunchback is definitely one of my favourites, and dare I say it, the songs are far more memorable than the overrated stuff in The Lion King. Not that I didn't like The Lion King, it's still great, but not the best IMO.
The Emperors New Groove is a funny one, it was at the back end of Disney's Golden era so I don't think that many people have seen it. The majority that have seen it love it from what I can tell though. It's not your classic Disney-style film, it's when Disney was evolving and the humour is different. So that might be another reason why it's 'underrated'. I think it's one of the best.
I always thought Hercules was really popular. Is it not? Saw that Nostalgia Critic geezer slating it on Youtube and i wasn't having that. The Bumder.
I remember really liking the Sword and the Stone when I was younger. Haven't seen it in years though.
Robin Hood I liked better when I was younger. I watched it recently and while it's still good, you can see why it's not considered one of the best.
I'll add The Aristocats in there. Doesn't get a huge amount of mentions but it's got some great characters. That Thomas O'Malley is one groovy cat.
And Everybody wants to be a cat is an all-time classic.
