The Wire is my favorite on HBO, followed by Game of Thrones. Both are great.

The Sopranos is great, Gandolfini is masterful, but some of the later seasons didn't hook me as much. One could say that about GoT also, but those first 6 seasons, man, always replayable. I just finished Season 2 again and loving it all over again.

Oz is always underrated, J.K. Simmons as Schillinger, man!

Breaking Bad/Better Call Saul is my favorite show of all time, I consider them one show because I love them both equally and they are in the same universe, albeit different times.
