No, this isn't a spoiler post about last night's episode - I haven't even seen the premiere of Season 5 yet (we gave up cable a year and a half ago)
However, in anticipation of the upcoming season I rewatched the first episode of Season 1 and the last episode of Season 4. I forgot how much I love Don Draper!! It was really interesting to see how much the cast has changed in the past 5 years, too.
Anyone else a Mad Men fan??
