Black Mirror -- Season 4

[cranefly]

Of other seasons, I'd highly recommend White Christmas.

Another good call.  Very enjoyable but I did guess the mcguffin as soon as the second character began telling his tale.

You peeked, didn't you.  Defying the sanctity of White Christmas, you crept down the stairs and peeked through the banister and saw the mcguffin.

Now you'll claim you don't live in a place with stairs and never did.

Hmmm.  I'm vaguely recalling going up stairs at your Daly City digs to perform a Cthulhu summons one Halloween...
