Battlestar Galactica, The Shield, The Sopranos.
Just sayin'.
No. Really.... no. I mean I've watched some of it and not disliked it but... not the same.
I see you and raise you;
The West Wing & The Wire
The Wire - watched the first series and it just didn't grab me. I can't bring myself to watch any more of it because the first series was so unmemorable that I'd be instantly lost
:edit: and yeah <3 The Shield <3
I'm not knocking the quality of
The Shield,
Battlestar Galactica,
The Sopranos. I've watched them all and very much enjoyed them, thought they were outstanding shows; you have to include
The Wire with that list too.
I'd be tempted to add another few shows as well;
Band of Brothers,
The Pacific,
Boardwalk Empire,
Rome ... [insert more here]
I am of the opinion however that
The West Wing for it's first ~4 seasons is unparalled in terms of quality; the rest of the show (half way through five through to seven) is at least as good as some of the others mentioned.
Dexter is brilliant, but I don't think it's quite as good as the others mentioned, I enjoy it hugely though, it's a brilliant concept.
A Game of Thrones is a really quality show too.
The Walking Dead however, leaves a lot to be desired, first season had some really good moments, but I found it slightly 'meh' over all. Not in the same class.
This is all my opinion, I'm posting after a drink too; so I'm not sure why I've written such a lengthy reply. There are probably many other shows I've missed out haha!
