I only recently watched this movie for the first time and found it to be a wonderful tale, although a different departure for Disney. I have read the books, The Chronicles of Prydain, and count them as being one of the best fantasy series' ever written. This movie is called The Black Cauldron but is really a combination of that book and The Book of Three. However I'm not going to sit here and compare the movie to the books. That would be a travesty.
To begin, the animation of this film is simpley breathtaking. This was the most expensive animated film of its era and it is definitely noticeable. The juxtaposition of color and darkness bring an eerie feeling of happiness mixed with foreboding and dread.
