From the hellish revelation in The Good Place to a certain blood-soaked wedding in Game of Thrones, these TV twists changed their shows for the better. Television is one of the best mediums for plot twists. A feature-length movie is confined to a couple of hours, so it can only really pack in one big surprise. Novels can be a great vehicle for twisty storytelling, but they require so much scene-setting that authors have to limit their twist quotient. But TV shows tell their stories visually, in installments, and on a massive canvas, so they can really shock their audience.
