Yet another reminder that the Dennis Wheatley novels may well be a very good read (or they were, many years ago) but that they invariably make (or are made into) pretty crappy movies. I don't even remember if I actually read "The Haunting Of Toby Jugg" myself or just have an awareness of it and think I did, so I can't compare in this case and just took the movie on its own merits.
It was ostensibly very well made (props, camera-work, location, lighting &c.) and the acting is difficult to fault, in fairness, but disappointingly the storyline was not entirely free of some fairly well-worn clichés and dragged on without going anywhere much for so damn long I was ready for just about any ending just to get it over with. Which is just as well - the ending was such a mess it was almost a case of 'Times's up, please hurry up and vacate the lot, we need it for someone else!' and it was neither particularly satisfying or shocking when it did finally arrive....
The whole thing was pretty much a letdown like a sandwich with little or no filling - a pity really, it could have been so much better if it had tried a little less hard to be weird and suspenseful!
