Yes, it gets better..and the show moves forward nicely.Does it get any better or is it pretty much like the first two episodes?
Since the seasons are so short, there is none of those filler episodes than many other longer shows have.
I have seen seasons 1-3 so far

I agree 100 percent with this statementIt's like a book. You can't judge after only a few pages. Give it time.

The show really rewards if you follow it.
This is very true..butt he is damn interesting character to follow(not without soul)..Don's a philandering asshole a thousand times over..
and I think he has become more responsible as the series has moved forward, though you cant take fish out from water..
The cast is great..besides IMHO these characters evolve very nicely, even during the first season. And they even might surprise you.At this point there isn't a single cast member that interests me, they are all hum drum and boring
Alicia, could you explain bit more of why these things bugged you so muchIt was just boring and while I understand it all goes hand in hand with the time and setting of the show all the blatant sexism, cheating and silly enough the smoking all rubbed me the wrong way.

I think is great that the show is period specific in tons of its details.
