The good thing about American Horror Story is that each season is a complete story and you don’t need to watch them all. Except that’s not quite true. There ARE elements that carry across different seasons, and Apocalypse picks up a number of threads in a way that’s both satisfying and irritating. I’ve watched six of the previous seasons, but that doesn’t mean that I remember them and there were quite a few times that I was clearly missing some back story which was a bit frustrating.
However, the threads that are picked up make for a much richer story and even if I didn’t necessarily follow all the connections, I could still appreciate them and get some satisfaction from them. The various timelines were played out well, working in large steps rather than muddling them all up made that aspect easy to follow at least, gradually adding explanation and depth without having to keep track of who-knows-what confusion. Actually, given how many settings and characters there are, it’s surprisingly coherent. The cast is full of familiar faces from other seasons, and it’s a credit to the actors that even when they end up playing multiple different characters over the span of Apocalypse, it still somehow works. (Wikipedia has an interesting table of who plays who in each season, but there are mild spoilers there).
The series was certainly compelling and entertaining but I can’t say I was ever particularly horrified. Other series have managed to be thoroughly creepy and disturbing, or deliver effective jump scares, maybe I’ve just become rather casual about gore, or this level of horror has become average for television. For the most part I didn’t feel the emotional connection to the characters that would be needed to feel lost in their awful situations, maybe that was related to me not being able to remember much about the previous times we saw the characters so I didn’t have that established relationship with them. But I still found it a really engaging season, I watched all ten episodes in two sittings, only interrupted by the need to sleep, so they’re clearly doing something right.
