Okay, so it’s Hammer and we are firmly in British horror territory here as a professor and some students go to an old house and delve into the world of parapsychology and, if you can get past a couple of bits of silliness (mainly an ‘experiment’ seemingly so cruel at the start that I don’t believe the central character would join it in the first place) , it’s a decent watch even if a bit derivative, but it’s genre so that’s half the fun.

The gimmick in this tale is a theory that paranormal activity is an extension of mental illness and the always great Jared Harris brings just the right amount of gravitas to the Professor role (you know, well-meaning but too invested etc) to keep the film going, whilst Sam Claflin’s curiously muted lead, a character that stands to the side of the action, makes a nice change of pace.

The use of 8mm and 16mm flavoured excepts help keep things interesting even if it does make you hanker for the atmosphere that shooting the whole thing on stock would have produced.
