For three seasons, Sterling Cooper has sold Lucky Strikes, Hilton hotels, and Belle Jolie lipstick. And for three seasons, AMC has sold us Mad Men, in an effort to re-brand itself as something greater than the home of not-so-old movies. Sometimes the sell has been too ham-fisted, and sometimes we’ve resisted. But after the fireworks of that spectacularly satisfying finale, we can no longer deny that we’re watching one of the most bold and unpredictable shows to ever air on television — and that AMC has given Matt Weiner full creative license to go for it.
