I think this 1940 film is very great. I love the music and the art style and it feels very alive. I'm impressed that they drew every single scene and made it a 2-hour film. Granted, at times the movie can feel slow and boring, but that doesn't make it a bad movie. I also really like the short with Sorcerer Mickey. Overall this film is one of the best that Disney has made.
I highly recommend.
