Episode: "The Flood" (605) Weaving historical events into the drama never feels like "Mad Men's" primary concern, and that's a good thing. So it was unusually awkward when the aftermath of the assassination of Martin Luther King Jr. took up so much screen time to seemingly so little purpose in "The Flood." The terrible news breaks 12 minutes into the episode and despite a few great moments (Pete borrowing Trudy's use of "shameful" in his argument with Harry, Don and Bobby's trip to the movies to see "Planet of the Apes," Ginsberg's father urging him to find a girlfriend, Don's monologue to Megan about his children) there's a lot of time devoted to characters watching TV and having no earthly idea what to do. A natural reaction, but not so great as drama. And then there's Roger's oddball friend Randall Walsh (William Mapother), who seems to visit from another planet (or show) entirely.
