The Man from Button Willow (1965)

I have to thank Michael Sporn for digging up this underrated gem.

George Orwell's Animal Farm (1954)

This was found by Raoul Duke from ConceptArt.org, and I liked the first fifth of this so far.

The Phantom Tollbooth (1969-1970)

This was Chuck Jones' second feature that he directed, and I do recall seeing this when I was six or seven. However, Chuck thought it was somehow a good idea to make some last minute tweaks to his liking. If that wasn't enough, he just got worse and worse after this was made.

Song of The South (1946)

Now here's the most maligned movie that Disney has ever produced. A lot of people misinterpret this as racist, but it was never intended to be such. For the record, I'd rather watch this over whatever Disney, Pixar, and Studio Ghibli are coming out with these days.

Wizards (1977)

Michael Barrier has criticized Ralph Bakshi for this and Lord of the Rings when they hit theaters. However, Bakshi did these for the same reason he did his city films: to change the kinds of stories that animation had told considering that his city films were being tossed out due to controversy. Edit: Here's Barrier's scathing review of Wizards: http://www.michaelbarrier.com/Funnyworld/Raggedy AnnReview/RaggedyAnnReview1.html
