this for the second time ever, and it had been 20 years since the last time. it's really quite good, though perhaps 20 minutes too long.
I can see why it was a failure with audiences at the time though. Mickey Mouse is featured in every ad and poster released then, so people probably thought they were gonna see a feature length mouse adventure.
and some of it's a little boring. naturally, the best bit is Igor Stravinsky's The Rite of Spring because of the pretty darn amazing and scary dinosaurs. Night on Bald Mountain is scary as well, and the rest are fun.
the animation is of course excellent. it does suffer from a sort of "disney look" to some of the cast, but that's to be expected.
for years this was the "lost Grail" of Disney movies on VHS, as no one had a copy. and when it was finally found, well, the real VHS and laser disc release in 1991 was nice to see. definitely worth watching, but I can't say I'm a huge fan.
