I like finding Nemo. There seemed to be more character development in that movie. You have the cowardly father, that is wants all the children named after himself. To the father that honors his wife' memory by giving the child the name she liked, and combating several sharks at once to find his son. Most Disney characters just don't develop that well. Instead most characters just have a sudden moment they switch that doesn't really make sense, but we just accept anyway.
Tarzan. Because it dealt with racial themes and also about family that raised you Vs. the place that you belong, and I think those are very emotional themes that impact a lot of people in real life and also reflects lots of real life situations.
Pretty much the only Disney movie I don't like is Wall E. Other than that all good choices, but Im going against the grain and say Frozen was awesome. It really highlights mental illness and how things aren't always as they seem. On a final note all Disney movies will be available on Netflix in the USA in September
Clever dialogue and storytelling Semi-realistic 3 dimensional characters georgeous artwork and animation Well crafted soundtrack Near perfect pacing Lovable relatable and understandable characters (If I go on I will melt with joy)
