But for a twisted minority, it has ceased to be entertainment and mutated into something far darker: a twisted inspiration for real-world violence.
Within just three months, two British killers who styled themselves on TV serial killer Dexter Morgan have been convicted of gruesome murders – while a 16-year-old obsessed with the show was convicted of attempting to murder a girl he did not even know in school.
The boy, who cannot be named for legal reasons, was just 15 when he approached his female victim in a corridor at Thorpe St Andrew School while wearing a balaclava, plunging a knife into her back before fleeing the scene.
His two-week-long trial heard he had a 'dangerous interest in killers and killing'; he created video compilations of both real and fictional serial killers, including Dexter, and craved what he saw as the 'admiration' they got for their crimes.
