In fact: the Man in Black, that's us. Viewers of Westworld, who watch episode after episode, season after season, cliffhanger after cliffhanger, yearning for that great revelation that will make us free, to an end that will finally offer us insight into the deepest secrets of being human.

Do we want that? Is the 'ultimate answer' not a miracle (finding the truth) and a curse (the end of the story) at the same time?
