I've only seen the first episode of Season 2 and I liked Anson Mount's Pike. For me, the appeal of Pike is that Discovery gets to fill-in the blanks for a character I've long been curious about. Plus, I became a Pike fan due to Marvel's Early Voyages comics, and later Bruce Greenwood's portrayal, so I am curious to see what Discovery does with him, how they add to his story.
From what little I've seen so far, I am pleased. However, I do sense a tendency to overcompensate with Mount's Pike to contrast him with Lorca. It doesn't quite fit the gruffer character from "The Cage". Certainly, Pike at that point was grappling with a lot of stuff, but still, Mount's Pike seems a little too chill compared to Jeffrey Hunter's depiction.
But from just the first episode, I do like Mount's Pike and I would like to see him in a spin off show, perhaps aboard the Enterprise or on another ship after he leaves the Enterprise. I would be fine if they found some way to keep him as captain of the Discovery. Then again, if they placed Number One as captain of the Discovery I would be okay with that too. (I am looking forward to seeing Rebecca Romijn in the role).
