I agree with
@Matt_Black. If you want blatant racism, you'd be better served by
Birth of a Nation or even
Gone with the Wind. Song of the South was made with the best intentions, from everything I've read about its development. And it features some the most charming animation the studio ever produced. I think the characters can stand on their own without necessarily being associated with the film in which they originated.
"Song of the South is RACIST! It's so offensive it was banned!" is a knee-jerk reaction, popularized by the internet. Give the film a watch. It's no masterpiece for sure, and is a bit sappy in parts, and suffers from the admittedly mundane/vague plot involving the human characters. But it does feature some wonderful performances, namely James Baskett as Uncle Remus-who is just a delight, and everything that character should be. He also voices Brer Fox, and a host of others-he was just a ridiculously talented man. And the songs are wholly enjoyable. So much so, I actually hunted down a record and ripped the audio to my computer. For me, the questionable/dated elements are vastly outweighed by the good. And remember: The film doesn't say it outright really, but Uncle Remus and his companions are
share croppers, not slaves. A really important distinction to make: At one point Uncle Remus leaves the plantation, with no consequences whatsoever.
It also features seamless blending of live action/animation, which is impressive today, considering the available technology of the time. Really, if you consider yourself a fan of the Disney, you do owe it to yourself to see it at least once. (Not that I'd
ever encourage acquiring any media illegally. Never, never.)
It would be great if they could make something on par with popeye in the magic kingdom.
