If you want comedy Arrested Development, Curb Your Enthusiasm, Seinfeld, It's Always Sunny in Philadelphia, 30 Rock, The Office (UK)
Michael C. Hall ( Actor that plays Dexter) also played in Six Feet Under one of the best T.V Dramas and arguably the series with the best ending. It is a little slow paced and different but it is so good.
Hope It helps.
Maybe you'd like Mad Men.. or the Sopranos. They're in the same alley as Dexter and Breaking Bad.
Orange Is The New Black
House Of Cards
Supernatural
American Horror Story
True Detective, Ray Donovan. Californication.
The Walking Dead
American Horror Story
Orphan Black
Continuum
Mad Men
Lost is really good, one of my favorite tv shows and The Walking Dead is decent as well.
the wire
the sopranos
burn notice
covert affairs
haven
orange is the new black (netflix)
hannibal
revolution
boardwalk empire (omar from the wire is in this)
These shows were so unbelievably good I'm having a hard time finding anything that measures up, I'm not interested in game of thrones but I'm open to mostly anything... Dexter was the one I just finished and I'm feeling too attached to the characters in it to move on haha
