Best Horror Series 2021

Chucky and Midnight Mass fans may be surprised that those shows weren’t rated the best-reviewed Horror Series of 2021, since they were well received and got people talking. Instead, that honor goes to the Korean series Hellbound, a sleeper hit about celestial beings handing out decrees about who’s going go to hell, with all the strange dramatic ramifications therein. You’ll burn through the 6-episode first season.
