I don't see how anyone could class Bakshi's Lord Of The Rings movie as "good"...that movie has a better place in a rubbish bin instead of on the shelves....my favourites as a child were:
Secret of Roan Innish
Time Bandits
Secret of Nimh
Ice Pirates
The Muppet Movie
The Great Muppet Caper
The Dark Crystal
Flash Gordon
Willy Wonka
and several others....
