The Lion King -- one of the most memorable movies from my childhood and it has a high re-watch value. Also, the songs -- all of them -- are A++. Besides "True to Your Heart" (Mulan), this movie is the only Disney movie of which I've bought the songs!
The Fox and the Hound -- also known as, "I'M NOT CRYING, YOU'RE CRYING!" I don't watch this one often because I absolutely hate crying, but it still stands as one of my favorites. My heart is squeezing just thinking about it now, wtfrak
Big Hero 6 -- Just when I thought Disney stopped making good movies (yeah, I felt that way by the time this came out), BH6 came on the scene. That's all I really have to say.
