@MartyMcFly finished watching the Wicker Man (1970s) I saw that set up coming about halfway through with them using him as bait but it did give off some Midsommar vibes with the rituals and cult behavior. That 70s cinematography, fade out and pacingExpect top levels of suspense and twisted ideology..
I saw this in the cinema in the 90's and 6 years ago.
Midsommar >>>>> over every cult movie in terms of pacing, scenery, suspense, storylines.
