Baywatch Nights, 1995-97

All American Television / Everett Collection
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.
