Alex Trebek was the beloved face of "Jeopardy!" for decades, and he left some big shoes to fill after his death from pancreatic cancer. Once "Jeopardy!" tapped former champion Ken Jennings as host, they also added "The Big Bang Theory" star Mayim Bialik after she was a guest host for Season 37. Since the two began, they've been receiving backlash from fans of the game show, who have been very outspoken on social media. So much so that the show’s executive producer Michael Davies has weighed in on the criticism. "This show is so hard to host," Davies said during an interview with Vulture.
