I usually skip the Rite of Spring, but love every other piece. Probably because I was trying to watch the visuals too hard instead of listening.

But the important thing to remember about Fantasia is that it's not a coherent story, it's a set of shorts.

You can watch subsets, skip some, or really do what you want. Just watch Night on Bald Mountain/Ave Maria, or the Dance of the Hours, or whatever you want. And give Fantasia 2000 a shot. Not as good, but still fun. Firebird was great.
