For any who aren't aware the concept of the 'Magical Negro' was first popularized by writer/director Spike Lee in 2001 and describes a Black character, often a janitor or a prisoner or some such, who acts as a sort of moral center to aid the White characters in their journey towards self-realization or to attain some life goal. It's a well-established trope in both literature and film, but it's also a fairly controversial one not least because of that name...
