Mad Men isn't a show that really ropes you in instantly like The Sopranos or something might do. I suggest sticking with it, as it really draws you in heavily over time. It's very good, but takes a bit of patience to get into.
Fair enough.
I just didn't find the "I can't believe they just said/did that, because it's the 60's" humor all that funny. When it's just the odd joke, like the pregnant women smoking in a bar in Hairspray, it's cool, but if it's the show's big gimmick, I think it might start to get a bit old for me. Less funny, more like the old relative that makes everyone uncomfortable with their very non-politically correct verbiage.
I also didn't really didn't find any of the characters all that likable. I get that people making bad calls [spoiler:63wi3zfu]Draper with his life away from his family, or the new secretary sleeping with the asshole[/spoiler:63wi3zfu] makes for good drama, but if I don't like any of them more, I don't really care if bad things happen to them.
It's like when I read Macbeth in high school. I didn't feel like it was a tragedy at all. When he [spoiler:63wi3zfu]dies[/spoiler:63wi3zfu] at the end of the play, I was thinking to myself, "Good. The guy was a total d-bag, and got what was coming to him". I just don't have sympathy for people who know better.
I'll give it another go though.
Side-note: I did enjoy Akira Kurosawa's take on Macbeth in Throne of Blood. That guy makes good movies.
