I knew I'd have a good time with this one. I'd heard we were getting a horror themed episode directed by someone who worked on The Haunting of Hill House, which is one of my favourite horror projects from the past decade. (Checking Google now, and I see it was actually Bly Manor. Close enough.)
You can certainly see the same approach at play, and I thought it was very fun to see in Trek. I also loved the nods to other sci-fi horror, including that one scene in TNG Night Terrors that really hit hard when I was 7.
I feel like a bit more backstory on the Griffen might have been nice. She was the last ship built in the Pyris shipyards, which mined its ore from an ancient alien graveyard, and all ships built there met a bad end. Or something better than that. But I see those in this thread unhappy that it wasn't all explained with the sci-fi equivalent of a gas leak, so maybe the simple mystery approach is a good compromise.
Apart from the horror of it all, some nice character work, with Kirk being the stand out. Nice to see his early relationship with Carol. Or lack thereof. I wonder if they'll ever have occasion to cast her or if she'll be forever offscreen.
