['Mad Men' - 'The Suitcase']

"You know what? There's a way out of this room we don't know about."

In Sunday's terrific 'Mad Men' episode, 'The Suitcase,' Don Draper said that about a rodent in his office. But he might as well have been talking about himself.

The episode was one of the series' best hours and a sensational acting showcase for Jon Hamm and Elisabeth Moss.

If anything, 'The Suitcase' made the case even more strongly that, as I wrote last week, this is the best season of 'Mad Men' yet.

You've read Allison's review and Joel's take on the Mad Men season finale, and I'd just like to add that I think it was the best episode of any TV series I've seen in years. Brilliant, dramatic, funny, even exhilarating. Here's a behind the scenes look at the episode, including interviews with Matthew Weiner and the cast.
