This honestly produced film is quite clearly in line with these critically acclaimed "new wave of horror" films (a little too much in my opinion ...) and carried in particular by Ari Aster and Jordan Peele (I much prefer Robert "The Witch" Eggerts...).
Paranoia, fear and fascination of sects, atavistic intolerance of difference, even cannibals (!) ... All this is packaged correctly but unfortunately with airs of deja vu.
