It's the beginning of the end for Mad Men and what a show it's been. It's safe to say that Mad Men has truly revolutionised how we approach TV dramas - and specifically, soap dramas - and turned a former drama teacher into a serious talent. Jon Hamm returns as Don Draper, the advertising executive who has it all - except happiness. The final episodes are set in 1970 and, as showrunner Matthew Weiner promises, will provide a fitting end to a much-loved series. We've seen the first episode and here's what we took away from it - ROGER STIRLING HAS A MOUSTACHE NOW.
