"Ever since the dawn of time, Magical Negroes have been helping troubled white characters out of jams. It's one of the most overused tropes in cinema history, but whatever helps white people with their issues is okay with us.
The underlying message being, 'If white people are okay, then the world is okay. That's all that matters.'
The only purpose of the Magic Negro is to help the white character. Then he/she can be quickly dispatched and the white person can continue on to the end of the film, his/her destiny fulfilled thanks to the ever faithful Magic Negro."
There were only 9 films on the original list. I added the last because it seemed to fit right in...although Red doesn't disappear after Andy Dufresne's problems are resolved. He does have the magical ability of obtaining things, though.
