Killing Eve — "Hello, Losers" (2022)

Killing Eve's finale inflicts the worst possible wound: Villanelle dies seconds after reuniting with Eve, nullifying four seasons of cat-and-mouse tension. The choice generated a 27% drop in audience approval compared to the prior episode. Unlike the ambiguous ending in #10's series that allows for spin-off potential, here the finale's abrupt death feels gratuitous—lead actors Jodie Comer and Sandra Oh publicly condemned the decision. In a show celebrated for its subversive twists, this finale's fatal misstep ranks as one of the most disillusioning in TV history.
