My Take

Courtney Henggeler is proof that patience can be a career strategy. After years of guest spots, including the inspired casting of Sheldon Cooper's twin sister Missy on The Big Bang Theory, she landed Amanda LaRusso in Cobra Kai in her forties and quietly became the show's moral thermostat. Amid grown men relitigating a 1984 karate tournament, her dry, exasperated sanity kept the series tethered to reality, and I think the show works largely because of her. That she has since stepped away from acting on her own terms only deepens my respect; knowing when to exit is its own kind of artistry.
