Ben Travers of IndieWire wrote, "all around, the actors remain strong, including a number of new cast members. The Man in Black is a main character in HBO's Westworld, played by Jimmi Simpson and Ed Harris.Man in Black is a Westworld veteran who has been visiting the park for over 30 years. Where season 2 stumbles is its structure and pacing. But if this William is a host, then that means we don’t know what happened to William at the end of Season 2. Last we saw, he was going down into the Forge after Dolores and Bernard. William, also known as the "Man in Black", is both a protagonist and a supporting antagonist in the first season of the HBO show Westworld, as well as the final antagonist of the third season.As a young man, he is portrayed by Jimmi Simpson, best known for portraying Liam McPoyle.


But Westworld remains a glorious production to look at, and there are stretches where it feels invigorated by its new, expanded world—freer to breathe, relax, invent."
Trying to remember how Westworld left things at the end of Season 2 is damn near impossible.
