Breaking Bad. Personally found it the most rewarding (by far), and, from Wikipedia: (Season 5) After receiving three nominations for seasons two, three, and four, both halves of season five won the Primetime Emmy Award for Outstanding Drama Series in 2013 and 2014. The second half of the season also won the Golden Globe Award for Best Television Series – Drama and the Screen Actors Guild Award for Outstanding Performance by an Ensemble in a Drama Series in 2014. The season's Metacritic score of 99/100 led the show to be listed in Guinness World Records as the most acclaimed television series in history.[5]
