As a Jewish person. I'm gonna have to agree with you. It is instructive to look at these films with a modern eye and learn from them. One time, back in the 80's when my oldest daughter was a pre-schooler, I purchased a combo pack of VHS tapes of really really old cartoons. Some were in black and white... they included Lil' Audrey and Raggedy Ann among others. I was sitting there one day watching an old Lil Audrey cartoon with my daughter when I almost fell out of my chair and my mouth dropped to the floor as I was shocked at the way black people were portrayed. Not only were they drawn in a racist way, their accents were exaggerated and their roles were so stereotyped. I just couldn't believe it!! This old cartoon HAD to be from the 1930's based on the way the men were dressed and what the automobiles looked like. This however, was a teachable moment. as I explained to my daughter the problem with this old cartoon and how things have changed. We talked about just how wrong this whole cartoon was. The cartoons however, had plots that dealt with what a brat Lil' Audrey was! Everything else was ancillary. It was the backdrop to a long ago world that we can't believe actually existed.
I remember seeing Song of the South as a child. I loved Uncle Remus because he seemed so nice. You just wanted to sit in his lap and have him tell you a story. He was like the best grandpa ever! I'd love to have the opportunity to see this old movie through adult and modern eyes.
