MAGIC NEGRO:
This refers to a stock character of a wise black character who comes along and teaches a white protaganist an important lesson. Unexplained mysterious powers are a plus, but not necessary.
This term is tied up into a lot of racial analysis, and like "Mary Sue" I think it gets tossed around a lot when it doesn't really fit, but that's not why I'm ranting against it.
My issue with it is that if you look up anyone describing what it means, every single person lists Morgan Freeman's character in "The Shawshank Redemption" as a good example.
Two reasons this bothers me.
a) The character, Red, is written as an old fat white guy. The movie cast Morgan Freeman but did keep a line of dialogue about him being Irish.
b) Red learns the important lesson of the film (something about hope) from the Tim Robbins character. He doesn't teach the Tim Robbins character anything or do anything especially important (except give him an itty bitty hammer).
I think Morgan Freeman is so charismatic, paternal, and charming that he gives the feeling of his character being more in line with the "Magic Negro" stereotype than the character actually is. His character is almost the opposite of the stereotype, and if Tim Robbins had been a black actor, his character would have been the one to fit it quite well.
