I know, it's not very popular, but I loved the music and animations.
It was acid for my my little brain.
Fantasia is incredible because it's often either abstract and makes you think, or atmospheric and makes you feel. I used to love it as a kid because I was kind of a weirdo and I related to the emotions. When I watched it as an adult after having a kid and bawled my eyes out for that little "me". I appreciate it so much more now than I did as a kid. They also chose interesting, challenging pieces like Stravinsky's Rite of Spring.
"Fantasia 2000" was lackluster in comparison.
I saw it the first time when I was really little, either four or five years old, and the moment Stkowski's hands came down on the first note of Toccata and Fugue was the moment that permanent cemented the difference between pop songs and dedicated, classical music to me. I had no idea what was going on, other than that it was something different, and really, really special.
