It wasn’t enough for the makers of Hawaii Five-O to let viewers pick the ending of an episode last season, now they’re giving fans control over a full hour. CBS today unveiled its Fan Built Five-O initiative, a Mad Libs-esque stunt that lets the public vote online for an episode’s half-dozen key story points: scene of the crime, victim, murder weapon, evidence, suspect and takedown. After the polls close on Halloween, the show’s writers will use the winning elements to forge a script. Before production on the episode begins in February, fans will be able to weigh in on such things as wardrobe, props, music and the title. The series hula-ed over to Fridays this season, and after two episodes McGarrett, Danno and company’s ratings are down 21 percent in the demo compared with last year. But it’s up by nearly that percentage in total viewers (9.6 million) on the older-skewing night, which CBS is dominating. Hence the web-voted story ploy targeting the less chronologically challenged. And TV writers thought reality formats were a threat to their livelihoods. Check out the categories and options up for balloting after the jump:
