“Nest Of Vampires” (*1/2 out of four) was a trashy potboiler about a rogue MI5 agent (Tom Fairfoot) who travels to the underworld of England to find the people who killed his wife and kidnapped his daughter and subsequently uncovers a ruthless vampire cult (led by Chris Sanders) who are embroiled in child sex-trafficking and Satanic cult worship. Unpleasant mix of the slick and the sordid runs out of steam pretty quickly. Fairfoot’s strong performance is about all that holds this together. Sanders also wrote and directed.
