Good TV Shows to Watch?

I have seen quite a few. I’m looking for something really catchy that will keep me begging for more. It can be a little old, but nothing past 2000.
Here’s what I’ve already seen:
The Office
Dexter
True Blood
Deadwood
Pillars of The Earth
Spartacus Blood and Sand
Community
Breaking Bad
Heroes
Lost
Outsourced
Anything similar, along those lines, or even different is great. As long as it’s good! Help me out.
