If you were the least bit disappointed by “Antebellum” (and let’s face it, who wasn’t?), then “Spiral” (shudder.com), airing on AMC Network’s Shudder channel, might be more to your liking. By combining elements from classic modern horror influences, from Polanski to Peele, and adding some specifically queer twists, “Spiral” has the potential to make your head spin — in a good way.
