I've watched the first two seasons of Mad Men, and a couple episodes of season 6, but i don't get the show.
If you don't get a show in the first few episodes of a season, let alone the whole season, why would you continue to watch the next season? Then skip a whole bunch, restart watching at the latest season, and expect it to make sense, let alone 'get it'?
I caught a piece of Mad Men in the middle of an episode in its second season, was gripped in the first 10 minutes, and went back to watch from the pilot, and could not stop. I can't think of many productions from Hollywood that can match that.
Earlier in these few years i enjoyed .. (to name the most diverse)..House, Harry's Law, Garrow's Law, The Killing, Big Bang, Suits, Hannibal, House of Cards,
Srsly? Big Bang? Then you should watch Two and half men; Mad Men's not for you. I could barely finish a full episode of Big Bang, and I tried with different episodes before giving up.
House has been funny, even interesting at times, but more in the 'nothing else to watch, might as well'. I'd never watch it serially, or compulsively. Same with House of Cards.
