would Welcome Home count as cosmic horror?
i certainly think it has elements of cosmic horror, if only by way of employing the "humans are cthulhu" trope. i actually touched on this in one of my very first speculation posts on this blog - and probably a couple others, but i can't seem to find them right now.
i'm not sure it manifests exactly the way i described it in that post, but there's definitely been a pattern of "character glimpses the True Nature of their reality (i.e. that it is a construct of a different and much Larger reality) and promptly either loses their shit or hastily constructs a more 'grounded' explanation for what they saw to avoid losing their shit" in these last few updates. furthermore, from what we've read in behind-the-scenes/QnA posts, i Feel like there's a very good chance of a lot of the social commentary in welcome home taking the form of, like. "imagine how horrifying this western (or at least, white american) societal convention would be to someone who had no concept of it, and then imagine that person's horror upon realizing that they were made by said society and are forced to comply despite understanding next to nothing about it."
...y'know now that i write that out i realize it could also just apply to a lot of horror stories that feature racism/colonialism as a Source of the horror. i wonder if that's intentional in welcome home's case. hmmm.
anyways TL;DR: i wouldn't like, put welcome home on a bookstore shelf labeled "cosmic horror" but i would find it acceptable if it came up in a video essay discussing the genre conventions of cosmic horror.
