Baywatch Nights, 1995-97

David Hasselhoff simultaneously starred in Baywatch and this two-year-long spin-off in which he moonlighted as a private detective. The most fascinating aspect of the series is the way it turned into a completely different show during Season 2. Nights ditched the whole crime-fighting thing and focused on the supernatural. Vampires, demons and sea creatures suddenly and inexplicably began to appear around the beach in droves, scaring away bathers — and viewers. Then it was canceled.
