I'm currently rewatching the series and up until season 5 there isn't an episode I truly dislike, some obviously better than others but all in all they're in general essential to the story, I read a few days ago the Mad Men thread and it surprised me how many people complaint about season 3, I don't get what they were expecting but throughout the entire season many things happened and the show evolved from that point on.
Anyway, the one thing I realized I miss the most is Roger Sterling, his lines were always great, funny and delivered perfectly, read this exchange from the final episode of season five where he is trying to convince Megan's mother to meet.
Roger: I'm not asking for anything more than a little conversation, I swear.
Marie: I'll try to getaway on the condition that you lower your expectations.
Roger: Below conversation?
Game of Thrones
I love everything about it, even how different are the show and the books.
This year I was worried that story wise it wouldn't be as good as it has been, but season six was great, e.g. that Hodor revelation floored me, Polka summed it up perfectly:
"The hardest thing to do in any storytelling medium is create an emotional payoff that is simultaneously earned and unexpected."
ok, we know GRRM gave them that one but still they pulled off the entire season.
Larry Sanders Show
I've said it before, I think this was the show that started to change TV as we know it, funny and brilliant.
OK, this did change TV too IMO, it's a miracle that it was made on network TV.
Seinfeld and Curb
Those shows have made me laugh like no other, brilliant.
Probably the best show at handling tense scenes, both the shooting of Hank at the parking lot and the last 10 minutes of Crawl Space are prime examples of that.
Recent shows that I love unconditionally:
* The Knick - Soderbergh is a genius
* Hannibal - Fingers crossed that they eventually make season 4.
* Fargo Season 1. Malvo's character is a thing beautifully evil.
* VEEP. A satirical view at politics that is falling short on the insanity that's been this election.
* Leftovers Season 2. International assassin.
