_Enemy_ is the sort of movie that provokes thought more than enjoyment. Gyllenhaal gives a terrific performance—essentially playing two versions of himself—and Villeneuve’s direction maintains his signature stylish and atmospheric feel. The exploration of self-destruction, and how choices can have negative consequences, held my attention, but it functions better as something to ponder rather than a suspenseful ride. While the ending is intended to be unsettling, I wasn't particularly disturbed by it; that sort of imagery simply doesn’t faze me. I can easily imagine many viewers disliking it, though. It isn't unpleasant to watch, but it’s not something I would rush to see again.
