This movie has had such an impact on me when I was young for how beautiful some of the scenes were. There is so much work of beauty in every frame, the colors, the animation and storyline. Nowadays we don't have much stories of centaurs and gods in the sky or ballet dances of demons. Fantasia is a light-hearted poetry of fascination with nature and magic.
I loved the first and the last segments because the abstract and/or mysterious visuals fitted so well with the classical music there. Other animated pieces, though, were maybe too simple or a wee bit too childish and kinda devalued the effect of music (especially the parts with centaurs and Mickey Mouse) ...I wish someone remade it once again.
