Watched the limited series Midnight Mass on Netflix. Aside from some complaints I had about the quality of the limited CGI effects, and aside from the embarrassingly on-the-nose commentary on "Islamophobia" (and in a show that was otherwise extremely subtle!), it was fantastic.
If you like slow burn psychological horror, just watch it. Don't read anything about it first. That said, I had the show spoiled for me by some faggot here but still really enjoyed it.
I always saw that spaceship as almost an act of desperation. It was pretty small, it was made of junk "Blair" found, and it put me in mind of a lifeboat. But the point, of course, was that if it worked at all, the alien could possibly escape from the Antarctic, if not the Earth itself.
You're right: perfect movie.
