yeah the first two seasons were the best. the third was funny but not as good as the first two.
I actually think 1>3>2.
Season 1 might be my favourite season of TV ever. I thought 2 was better than 3 when I first watched them, but I'm re-watching season 2 right now and I think I prefer 3. I'll re-watch 3 soon as well though, so IDK, I'll see how I feel after that.
I'm a massive fan of all 3 seasons, though.
Also finished season 1 of Mad Men a few months ago, but I'm not in any hurry to watch season 2. I bought both on DVD, but it took me ages to get done with the first season. General consensus is that it hit its stride about 5 episodes in, and I'd agree with that, but it's a show I need to feel really motivated to watch. Definitely not as big a mark for Don Draper as a lot of people are.
