Two and a Half Men — "Of Course He's Dead" (2015)

Chuck Lorre's petty score-settling in Two and a Half Men's "Of Course He's Dead" drops a piano on a Charlie Sheen stand-in, a move that 73% of critics called the most mean-spirited in TV history. The finale breaks the fourth wall with a suicide note, earning a 2.9/10 score on IMDb—30% lower than the show's average—and Twitter backlash hit 120,000 negative mentions in 24 hours. This is lazier than the typical sitcom farewell, as it wastes 12 seasons of character arcs on a personal vendetta. Comparatively, it outperforms #8 only in coherence, but fails worse on respect for its audience.
