From The Good Place to Search Party to Crazy Ex-Girlfriend, the plot twist is no longer the realm of the TV drama, says Rachel Aroesti. “Partly as a ploy to rejuvenate the slightly stale sitcom format: surprises are funny, and a twist in a sitcom is doubly surprising because you don’t expect it to be there,” she says. “It’s also something that goes hand in hand with the long-brewing trend for high-concept comedy.”
