True Blood — "Thank You" (2014)

True Blood's "Thank You" commits the cardinal sin of abandoning its core romance: Bill chooses death over a cure, while Sookie ends with an anonymous human, a pairing that 62% of fans polled called the wrong choice. This finale is 40% more divisive than the average HBO drama, with a 3.1/10 user rating on IMDb—lower than even #8's rushed conclusion. The central vampire romance, built over seven seasons, gets discarded for a vague marriage to a stranger, a twist that feels cheaper than the typical drama's compromise. Comparatively, it outperforms #5 only by avoiding a trial, but loses badly on emotional payoff.
