What makes a great TV show intro? In short: music, metaphor, and mood. Ryan Hollinger explores the intro sequence in his Screen Smart series, expertly exposing the details we take for granted as viewers but become obvious on closer inspection. The serial killer drama Dexter is a particularly straightforward one—the main character's murdery personality shines through even while doing boring morning activities. Twin Peaks' is more subtle, balancing serene images of a rural logging town with an eerie green glowing font (see: Stranger Things) and music that is calm but ominous. Still others lean harder on music or stylized visuals, but for all the goal is the same: to tell you what tone the show has and to trigger a base emotion.
