The Leftovers, "Guest"
In its first season, "The Leftovers" was occasionally guilty of putting out episodes that worked more as a collection of incidents featuring the show's characters than as cohesive hours of TV. Twice that year, though, the show did episodes told entirely from the point of view of a single character: "Two Boats and a Helicopter," about the extremes Reverend Matt went through to keep his church open, and "Guest," where Nora attends a conference about the Sudden Departure and has an emotional breakthrough with the help of one of Holy Wayne's hugs. These two episodes were the season's most effective and powerful, with "Guest" being praised even by critics who otherwise hated the series, and it inspired Damon Lindelof and company to model all of the second season episodes the same way, though some of them will be told from the POV of multiple characters within a small group (say, just the Murphy family, or just Erika and Nora). It's been a shift to the show's betterment, and has allowed them to do completely crazy and wonderful episodes like this week's "International Asassin," which wouldn't have been one-tenth as good if it kept cutting away from Kevin's situation to advance the stories of other characters.
