I don't know what is going on in the preview for the "No-End House" season of Syfy's anthology series Channel Zero, but sitting through its 90 seconds without any knowledge of the concept is an unsettling experience – which bodes well for the show itself.
If the trailer leaves you wanting more information, here's the official synopsis of the No-End House season, which stars John Carroll Lynch, Amy Forsyth, and Jeff Ward:
Inspired by Brian Russell’s Creepypasta tale, Channel Zero: No-End House tells the story of a young woman named Margot Sleator, played by Amy Forsyth, who visits the No-End House, a bizarre house of horrors that consists of a series of increasingly disturbing rooms. When she returns home, Margot realizes everything has changed.
Channel Zero is executive produced by Max Landis and Nick Antosca, who serves as showrunner.
I didn't watch the first season of Channel Zero, which was a six episode telling of a story called "Candle Cove", but this preview of "No-End House" has me seriously considering giving this series a viewing now.
No-End House will begin airing on Syfy on September 20th.
