Tonight, HBO premiered the first part of Leaving Neverland, the long-awaited documentary detailing Michael Jackson's alleged sexual abuse of minors. Over a grueling, disturbing two hours (with the second and final part airing on Monday night), Wade Robson and James Safechuck explain their relationships with Michael Jackson as kids and outline the sexual abuse they allegedly suffered at his hand.

The graphic descriptions it presents have been unsettling audiences since its premiere at Sundance earlier this year, and one has to wonder what hearing these accusations will mean for the legions of Michael Jackson supporters the world over.
