There have been literally thousands of retelling of the Robin Hood legend, but it's no surprise that the Disney iteration is the best. By swapping out the main characters for cute talking animals and a badass folk minstrel chicken, the studio breathed new life into a story that had already been told to death. Also, it's probably the reason furries exist, so there's that.
Moana is a testament to just how far we've come. It marks the first time that a princess has ever been allowed to be the hero without having to prove herself. Moana is a badass from the get go because that's just the way it is. Combine that with an awesome soundtrack and scene stealing performance from The Rock, and you've got a bold new direction for the studio that makes us excited to see what's next.
I will say it right here and now: Hercules is the single greatest soundtrack in the history of Disney. There's also a story of some sort, but that's incidental. Have a listen to "I Won't Say I'm in Love" and tell me you don't feel immediately happier.
Lilo & Stitch is something of an oddball in the Disney canon - the artstyle is nothing like other Disney films, one of the main characters is literally a murderous bioweapon, and the music is largely sourced from actual pop music - namely Elvis. But the end result is something truly special - a story about outcasts and family and the meaning of sacrifice. Plus, as far as heartwarming catchphrases go, "Ohana means family" trumps "Hakuna Matata" any day of the week."
Okay, I gotta admit I'm surprised that this one was this high up on the list, but I shouldn't be. Emperor's New Groove is an underrated classic. Kronk alone would be enough to earn a spot on this list, but there's more to the film than just a lovable sidekick. What sets Groove apart is its sense of humor, giving you more jokes per minute (JPM) than any other other film in the history of the studio. Booyah.
