1. 'Lethal Weapon'
Some things aren't meant to be, and that's certainly the case for FOX's small-screen adaptation of Lethal Weapon. The show was on the cusp of cancellation after Clayne Crawford's toxic, behind-the-scenes behavior went viral. After replacing him with Seann William Scott in Season 3, the buddy cop drama was off to a great start. It was a shocker when the show's other leading man, Daman Wayans, straight up quit the series. Wayans cited the grueling filming schedule as the main reason for his departure. It's obvious that Lethal Weapon cannot survive Riggs and Murtaugh.
