OCEAN BEACH — “Terriers,” the gritty Ocean Beach-filmed comedic drama that’s had locals on a leash since its debut Sept. 8 has apparently lost its bite for FX Network executives. The network announced the cancellation of the original series after 13 episodes, citing an average viewership of about 500,000 per episode. With many locals remaining loyal to the series that stars Donal Logue and Michael Raymond-James, a rabid electronic petition campaign was launched to bring the series back — so far to no avail. The series centered on the two stars, who become unlicensed private investigators. The producers enlisted the help of dozens of local crew members and extras each episode, shooting largely in Ocean Beach but also all over San Diego’s most scenic and iconic locations. Officials with the Ocean Beach MainStreet Association lamented the cancellation in an e-blast to local merchants and residents Dec. 22, urging neighbors to keep the petition campaign going and to press FX Network decisionmakers for a return of the series.
