You have to identify genres.

Comedy - Frazier
Sci Fi - Star Trek TOS 66-69
Mystery - Twilight Zone
Adventure - Game of Thrones
Spy - Man from Uncle
Drama - Brideshead Revisted.

It's a tough question to answer... for me the answer is probably Firefly even though it ended too soon!

I'm going to have to say Star Trek TNG, not because it was the best TV show of all time, but because of the memories of that time of my life, the people I watched it with and the conversations we had about it.

I can't just name one but tied for first are.
Dexter.
Game of Thrones.
Battle star Galactica. ( the 2000's series, not the 70's show).

Doctor Who. Endless variety.

Farscape. Hands down.

1 soap
2 married with children
3 cheers
4 twilight zone
5 alone

Buffy the Vampire Slayer

Too many to mention, but here are a few in no particular order:

• The Big Bang Theory
• Project Runway
• The White Box Challenge (ran on HGTV for a short time)
• Moonlighting (before it jumped the shark)
• Murphy Brown
• Night Court
• Northern Exposure
• Saturday Night Live (the first five years only)
• Third Rock From the Sun

It used to be MAS*H, and I still love it a lot, but I'm inclined to say that maybe Supernatural has eked up there close to the top spot.

My all-time favorite is Buffy The Vampire Slayer. It truly had everything. And bonus points for the LOVELY Alison Hannigan.

SyFi remake Battlestar Galactica

Star Trek TNG,

South Park

Doctor Who. I've watched since about 1983. ?

The Gong Show

Weeds
The Americans
The Sopranos

Law & Order- Criminal Intent; Detective Gorens the shit

Mad Men. Seriously, nobody mentioned Mad Men?

Man, that's a though one.... I would say The Big Bang Theory. Reason being, by pure luck I was watching TV the day aired the pilot episode. I was pleased with the writing style and I thought right away it was going to be such a boomer to see it cancel the next season. Gee, did they proved me wrong !!!!.... My life have changed quite a lot and the show is still standing !!

Outrageously accurate, funny and satirical puppet show featuring rubber re-creations of prominent people.
And
Star Trek

Wheel of Fortune. I was a contestant on the show in 1997.

Dexter, except for the last season which was terrible! Also, a British sitcom from the early 2000's called "Coupling" kinda a British version of Friends.

Versailles

So many to choose from.

I think Breaking Bad and The Wire might be the two best shows I've ever seen. There is just something transcendent about them that elevates them from TV to art.

The Good Place may very well be the smartest show currently airing, mixing ethics, moral philosophy, pratt falls, and food puns in equal measure.

Person of Interest was an astoundingly good show that started with what seemed at first to be a paper thin premise for just another procedural. However, it quickly became one of the best science fiction shows ever made, delving into complicated issues of artificial intelligence, conciousness, and the surveillance state.

Brooklyn 99, started a little weak, but by the end of the first 7-8 episodes it had become less of a Andy Samberg vehicle and more of an ensemble that focused on the whole, wonderfully diverse cast.

Justified was a fantastic show and a prime example of the idea that every character can be fully formed, well rounded and entertaining, no matter how small. The writing was smart, the energy between the actors was downright electric, and the dialogue was razor sharp.
