Zach Gilford as Riley Flynn in ‘Midnight Mass’.EIKE SCHROTER/NETFLIX
The ideas at the root of this show scare me to my core.
There is darkness at work on Crockett Island.
Some of it is supernatural, but the scariest is born of human nature.

“But this show is about something else as well… faith itself.
One of the great mysteries of human nature.
I hope you enjoy our song.”
