Hannibal (2013-2015)

Bryan Fuller's visually stunning psychological thriller transformed Thomas Harris's characters into high art television, but NBC's consistently low ratings of just 1.3 million viewers in season 3 doomed it after three seasons despite universal critical praise. The show achieved a 97% critics' score on Rotten Tomatoes, yet it was 60% less watched than network dramas like This Is Us. Its cancellation stings more than #8's because Hannibal had a committed fanbase that has repeatedly petitioned for revival. The series' unique visual style and 6 Emmy nominations showed its cultural impact, but network economics ultimately killed it, leaving the story at a haunting cliffhanger.
