It's not so much the content of the film itself, but more of it's basis. Yes, Uncle REmus is portrayed in a positive light, but that is a perpetuation of stereotypes meant ot make the freed slaves seem non-threatening, in the sense that they weren't competition and that if they keep to their place they everything will be okay. So, there are problems with it. That said, there is also the consideration that the idea that a former slave could not posssibly have been happy in that situation is a very narrow way of thinking - happiness is a state of mind and can be achieved despite dissatisfaction with other aspects of life - but that's getting into deeper thoughts than are germaine to this film. Honestly, I'm not really sure I'd call it a very good film - it's mediocre if anything, which is why it's probably not worth rehabilitating anyway.
