What TV program can you rewatch over and over and still enjoy?

[Soubriquet]

I have quite a few.

The 100
Charmed
Buffy the vampire slayer
Firefly
Izombie
Agents of Shield
Law and Order SVU
Brooklyn 99
Supernatural
Dollhouse
Call the Midwife
Vampire Diaries

Will probably add more when people add theirs, but if I don’t know what to watch, or just want a comfort watch, I can put any of those on and be happy.

Foyle's War.
Game of Thrones
I, Claudius

Granchester
Cranford

The Americans.

If I'm actively watching, I pick up new details/nuances every time. If I'm passively watching/have it on in the background - the soundtrack! The fashions! The scenery! (OK, it's mostly DC, but there are some spectacular departures.)

Room 101, hosted by Frank Skinner. I'm rewatching it and am in tears of laughter. 🌹

A pea soup in a brewery!

The IT Crowd
Homeland
The OA
