The Rescuers Down Under (1990)
Unlike most sequels, The Rescuers Down Under outdoes its predecessor with better animation, more developed characterization, and an even stronger plot. Bob Newhart and Eva Gabor reprise their roles as Bernard and Bianca and John Candy also joins the cast as the unforgettable Wilbur.
Candy gets some of the best scenes and is the perfect dose of comic relief for this rather suspenseful plot.
The Rescuers (1977)
The Rescuers' success is largely due to its excellent character creation. The plot is somewhat dark, with Medusa snatching up Penny and ridiculing her of not being worthy of adoption. Thankfully it adds a good amount of comic relief in the form of Bernard and Bianca, the spunky agents of the Rescue Aid Society.
The action that runs throughout is impressive and the stakes are made high enough to keep the audience on the edge of their seats.
The Many Adventures of Winnie the Pooh (1977)
Thankfully, The Many Adventures of Winnie the Pooh is not a package film but is essentially three short films stitched together with some added material to help it run more seamlessly. Even if the voice of Christoper Robin is pretty inconsistent thought, it somehow not as bothersome.
It's possible that the emotional impact can only be truly felt if you are familiar with Pooh and the gang. If you are not, it sure is shrug-worthy.
Hercules (1997)
The film definitely takes some poetic license in casting Hades as the villain simply because he is the ruler of the underworld. That aside, the film is still pretty great and follows our hero, Hercules who finds fame, but then starts to feel the burden of celebrity.
You can tell how Disney explored certain things it hadn't until this point in terms of themes and style. While the animation is more cartoon-like in appearance, the content feels almost adult.
One Hundred and One Dalmatians (1961)
Disney's most well-known villain, Cruella De Vil, made her debut in this film. Her distinct and heartless desire to skin puppies for coats makes her forever stand out. In fact, watching her coldly purse the dogs makes even this animated film hard to watch.
Obviously, being a Disney film and all, the dalmatians survive. It's immensely satisfying seeing these canines join forces to destroy evil.
