Watching on Amazon Prime... It's the one with two stories in one season. The second feature is a story about aliens and their attempt to impregnate humans, over the course of many decades, to create a human-alien hybrid. There's a hilarious appearance by Sarah Paulson as Mamie Eisenhower. In short, a group of young people, two men, and two women, get abducted by aliens and impregnated (and this includes the males, whose biggest worry seems to be "how is this baby going to come out of me?") Three of the four youths have imperfect hybrids which are immediately killed, along with the parent. The fourth, a woman, delivered a perfect hybrid. The aliens then immediately remove her head (replacing it with some sort of robot head/metal ball, to keep the body alive) and keep her body, so they can rapidly breed more hybrids which will then take over the earth.
The whole " keep the body, remove the head" seemed so deeply misogynistic. Why not have one of the male characters deliver the perfect hybrid? Why was it the woman who was turned into a literal baby making factory? And this woman, btw, was a semi Luddite, who was trying to reject technology I'd love to discuss with others who have seen this season of AHS.
