Phil A. Mignon’s review published on Letterboxd:
Possessor comes off pretty much as I expected. Cronenberg's the kinda guy to let a harebrained idea fester and mutate, and the film itself feels like a painful struggle with an abomination which has outgrown its inception. It's full of stumbles, uncertainties, and half-measures, but the strength of the initial conceit is more than enough to carry a threadbare narrative like this forward. I don't mean this to discredit the young flesh wizard's directorial snazz, as his off-kilter clinicality and eye for the off-putting make his lofty ideas seem more concrete and his horror images seem more extreme than they really are.
