The Butter Battle Book

Bakshi's oeuvre couldn't be more diametrically opposite than Dr Seuss's work: While the former is mostly known for his involvement in raunchy, adult-aimed animated films, Dr. Seuss remains to this very day as a wholesome icon of family entertainment, similar to Mister Rogers.

The ultimate result here is closer to Seuss's than Bakshi's, being a rather whimsical special with some darker undertones (In this case, a Cold War allegory) Apparently Dr. Seuss considered this animation the best adaptation of his books, and while I personally think that The Lorax short film from 1972 is more deserving of that title, this was an interesting watch anyway.

It would have been quite fascinating to see another collaboration of Bakshi and Dr. Seuss.

One more thing: The "Pg" rating (Assuming this is not a mistake from Imdb part) is ridiculous. This is pretty much a "G-rated" work, and honestly it feels more harmless than some G-rated Disney films such as The Hunchback of Notre Dame. I guess Bakshi was totally right when he said the rating board hated him and his work.
