No particular order, and this is more “what I’ve watched recently” and is sitcom-heavy, but so be it.

Letterkenny: rapid-fire timing, and available on Hulu recently.

Unbreakable Kimmy Schmidt: It’s not 30 Rock, but similar absurdity and outrageous characters.

Marvelous Mrs. Maisel - Well written and well acted, even the worst characters have moments where they are sympathetic.

Drunk History - every now and then, you might learn something from this, even as they work through the booze.

Mystery Science Theatre 3000 - Working through the new series now, but I still have my favorites from the original series.

I'm sticking to fiction here, so no competition shows, so-called reality programs, no science or how-to shows, etc.

Older shows

• Buffy the Vampire Slayer (comedy, action, drama, romance, all well done, something for everyone, bear with the first season though)
• Picket Fences (drama, ethics, some humor, very smart)
• Star Trek: The Next Generation (science fiction, humor, action, ethics, philosophy)

Cartoons

• Rick and Morty (science fiction, philosophy, comedy)
• BoJack Horseman (comedy, drama, all the feels)
• Archer (comedy, action, absurdity)

Recent shows

• Westworld (science fiction, philosophy, action, suspense)
• The Good Place (comedy, drama, ethics, loads of fun)
• Black Mirror (anthology, surreal, philosophical, horror)

Game of Thrones.
Breaking Bad.
The Sinner.
True Detective.
Vikings.

Dexter
Shameless
How to get away with murder
Breaking Bad
Sons of anarchy

Buffy The Vampire Slayer (always my first choice)

   The first seasons are random nonsense, but the new ones are worderful social critics double down episode is the perfect description of the Trump effect for example.
