Excellent casting & exquisitely shot. Massive nods to british folk horror which gives it a eerie sense of menace throughout. The main protagonsists are utterly detestable as are their multiple victims, (well , initially at least) & are incredibly well realized. The plot is uncomplicated, it's not a requirement , as all the enertainment is derived from characterisation. Don't watch this film if you are lacking a sense of the darker side of humour, or you generally don't appreciate the shockingly absurd.
