Nope, this isn’t ET, The Extraterrestrial, not by a long shot. Guest reviewer Lee Broughton offers an assessment of Harry Bromley Davenport’s British cult sci-fi shocker of modest means, a show that would be pure exploitation if not for some creditable performances. It’s nasty but has a basic competence and is not just more cynical grist for the mill. ‘Phone Home,’ my Aunt Fannie: sometimes the difference between a thriller like this and a higher-profile classic is just pretension. On Blu-ray from Second Sight (UK).
