Vacancy: Just days after the creators of Do Not Disturb sent out a letter to TV critics apologizing for “being the perpetrators of such bad television,” their show has become the fall season’s first cancellation. According to EW’s Michael Ausiello, the Jerry O’Connell sitcom (which aired only three episodes) will be replaced by reruns of ‘Til Death. Elsewhere on the dial, Ben Silverman pet project Knight Rider premiered third in its time slot despite having the highest viewer awareness of any new NBC show. Perhaps audiences realised that KITT is kind of a bitch? [EW]
