If you need a gif of Pete getting punched in the face over and over, here it is.
It was funny that right as I declare that I have come around on Pete and kind of love him, here's an episode where I hate him again and then he gets punched in the face! It all works out.
You know, I wasn't sure how I felt about this episode (I kind of didn't like it? But I think that was because I had just come home after seeing Cabin in the Woods so watching people in an ad agency just was not very engaging), but Todd VanDerWerff makes an astute observation:
The thing that I love most about Mad Men is its sense of confidence. Even when the show is doing stuff I don’t really like, it moves with a quiet sense of self-possession. It’s certain that it’s the greatest damn show on television, and there’s nothing you could say that would dissuade it of what it’s doing. Mad Men is one of the most fun shows on TV to write criticism about because you’re totally aware at any given moment that Matt Weiner and his collaborators just don’t give a shit what you think. They’re going to make the show they want to make, and you’re free to think about it as you will. That confidence is both charming and occasionally over-powering.
I would replace "over-powering" with "off-putting," but yeah. He then goes on to shower the episode with praise, as is his wont. The AV Club reviews always help me appreciate the episodes for what they're doing and what I may have missed below the surface.
