3. Don Draper Hits Rock Bottom
Mad Men, AMC
Mad Men's darkest season had its ups and downs – Sterling Cooper's merger with the rival ad firm of Tedious & Turtleneck was a dramatic void that threatened to swallow the rest of the story. But the season ended with a flurry of great episodes, as Don Draper trashed his career as well as his marriage. The final scene was a real heartbreaker: Don hits the road to show his teenage daughter the whorehouse where he grew up. They stand there on a street corner in Pennsylvania, looking like a couple of lost kids, to the sound of "Both Sides Now." She lifts an eyebrow at this dad she hardly recognizes. He wonders if she's as doomed as he is. Neither says a word. What an unforgettable moment.
