Angel has been named one of the ten worst shows for 2002-2003 by the American Parents Television Council.
The PTC's aim is to bring 'America's demand for positive, family-oriented television programming to the entertainment industry.'
As such, the body is akin to the Mary Whitehouse founded National Viewers and Listeners Association in the UK.
As well as campaigning for family-friendly entertainment, each year the PTC names and shames the programme it sees as failing to fulfil its high standards.
Here's what they had to say about Angel:
"This Buffy the Vampire Slayer spin-off stars David Boreanaz as a centuries-old vampire searching for redemption while fighting evil in Los Angeles.
"Despite its young target audience, Angel routinely features gory violence and graphic sexual encounters. Scenes frequently involve intense fighting, blood, decapitations, and more. The series also sends a dangerous and irresponsible message to teenage fans by equating violence with sexual excitement. In many scenes, characters become aroused by fighting."
Elsewhere in the poll, the worst offender was CSI, with Will and Grace number eight, and Friends ninth.
