Breaking Bad hands down

Game of thrones

Currently GOT, but in the recent years it has to be The Wire.

Game of Thrones and Vikings.

The Vikings season finale yesterday was epic, in my opinion.

True Detective (amazing screenplay, amazing acting, amazing directing, amazing cinematography, amazing music)
Twin Peaks (very good atmosphere, Lynch style)
Breaking Bad (Very powerful, so much suspense)
Lost (I hated the last season, but overall I loved it, the characters, the story, one of the tv shows you used to be a part of as a character, I really wanted to live a day on that island, I rewatched it without the last season)
Dexter (Amazing start, the first season is probably my favorite season from any tv series, the last season are awful, especially the last one and probably the worst ending ever imagined since Lost, both had the same problems, the writers didn't know what to do, they were too surprised by the success and didn't deal with the pressure of finding the perfect ending, Dexter has some bad season - 6,7,8, but 1 and 4 are amazing)
Bates Motel (I can't say it has the best possible quality, but it's good and has amazing potential, I like the story, I'm a big Psycho fan, I don't like Highmore, but Farmiga is brilliant, I also like Olivia Cooke, talented young brit)
Married with Children (probably my favorite sitcom)
