Some of these might fall under the category of classics for some, but I'm going to add them anyway...
Newsies - I've seen this movie at least 400 times. I know pretty much every line, can sing the songs and dance the dances... you name it, I know a lot about this movie.
The Great Mouse Detective - So, so, soo underrated. I adore this movie.
The Three Caballeros - When I was four years old I wanted to rent this movie every week.
The Tower of Terror - I love this little movie. I searched high and low for it after it was made available for purchase and finally found it at WDW. It was a very happy moment.
The Aristocats - I really love cats. Especially when they're the good guys!
Robin Hood - Really lovely all around.
