John Kelly’s review published on Letterboxd:
Struggles a little to find an emotional foot-hold. Or maybe it just doesn't care? The film gives us two minutes of **heavy** foreshadowing and we're already into the meat of the film. Both Jesse Eisenberg and Imogen Poots are both really likeable as actors, but when there's no attempt to humanize their characters, it leaves the audience feeling alienated. Even the sex scene felt emotionless and mechanical (maybe that was the point, but it sure didn't feel like it).
But it's a solid, if not particularly deep, premise. And it's well executed. Around an hour in, I was afraid the film was going to run out of steam considering how little set-up was involved, but the third-act turn was shocking and genuinely thrilling.
