And the best show ever... my prediction...
D&D - Season 20!

Viewers had mixed response to this season—but it was a critical hit

The first season of Lost would have been a phenomenal standalone if the show had been canceled. It basically ended on the idea that it's turtles all the way down, and you can never answer anything.

Yikes you guys remember which specific seasons where which in old TV shows way better that I can!

 

[Mallus]

Here's a few more recent shows, because I can't remember that far back anymore...

The OA, season 1
Sense8, season 1
Hannibal, seasons 1 & 3
Pushing Daisies, season 1 (Did it get more? I can't remember!)

And one classic...

Star Trek (TOS) season 1

Some repeats from others:
Buffy - Season 3
True Detective - Season 1
Hannibal - Season 1?
The Good Place - Season 2

Some new ones to consider:
Twilight Zone - Season 3 (I could easily be talked into Season 1 for this)
The Simpsons - Season 6
Monty Python's Flying Circus - Season 1 (I could easily be talked into 2 or 3 instead)


Alternatives for your consideration:
Ed Sullivan - Season 17 (The Beatles first three appearances, but lots of other good stuff, too)
Jeopardy - Season 20/21 (The Ken Jennings run)
Rick and Morty - Season 1
South Park -Season 1
