The most clichéd, unimaginative slasher pic I’ve ever seen. This is like if AI wrote a slasher pic. Six friends but a remote fixer-upper in the English countryside where there is, of course, no cell reception. Soon the local inspector comes around to tell them the history of the house: the last owner came home one day and “for reasons unknown” killed his family with a hunting knife—and he, of course, just escaped from a mental institution. The killer sneaks into the house wearing, of course, a distinctive homemade mask to which he has gone to the trouble of adding a mechanical mouth that opens and closes to produce a chattering visual effect, because, movie, and, of course, stalks them around the house and stabs them one by one, because, movie.
