Being a big HP Lovecraft fan since I was a teen, I was really excited about this show and over the past couple months it's been really impressive. It's such a weirdly cool hybrid story that weaves together Lovecraftian elements and themes with a story centered around a mid-50s Jim Crow environment. My wife knows nothing of Lovecraft and the Cthulhu Mythos, and she loves it, so I don't think it requires a deep understanding of the Lovecraft side.
