Hammer films had by 1972 clearly some problems coming up with new and fresh ideas. Their old style monster movies were beginning to show their age and the formula had been remade too many times (ie. Dracula AD 1972). So some experiments were made. "Captain Kronos" is one and this one another. The story moves very slowly in the beginning and what is happening is never really quite clear. The story about one family's inherited madness is intriguing but never fully developed. And those expecting some gory horror movie will be very disappointed, because for the most part, this is a rather slowmoving psychological study with added chilling elements. The biggest drawback here is the pace, which is non-existent for three-thirds of the movie. The final twenty minutes or so are more satisfying in that sense. Robert Hardy is also not a bonus, overacting like mad. But there are compensations. Other performances are very good, like Patrick Magee as the mock-psychiastrist and Gillian Hills as the young and maybe mad daughter of the family. And the basic plot IS interesting! A remake with a revision of the script might do wonders. Arthur Grant behind the camera does a great job too, contributing his usual skill and thereby making everything look more expensive than it really is. The art-director knows what he is doing too and the score by Harry Robinson is excellent (he really was an underrated filmcomposer).
