Billions on Showtime at 9:00pm ET. Fifth season summer finale.

Grantchester on PBS at 9:00pm ET. Fifth season premiere. Your charming cozy-mystery set in mid-century small-town England is back to take your mind off all of everything. Temporarily.

I Know This Much is True on HBO at 9:00pm ET. First season finale.

Quiz on AMC at 9:00pm ET. First season finale. There's three episodes, it's a bit grand to call it a "season". Especially since I don't think there's going to be another one, but there's a lot of television semantics that don't make a whole lot of sense and no one can tell me exactly what a "mini-series" is so we'll leave that alone for now. Really, having seen the first two episodes it feels most like a TV movie someone chopped into three parts for some reason.

Insecure on HBO at 10:20pm ET. Fourth season finale.
