Two horny millennials, Gabi and Martin, listed as DTF in their social dating aps, meet up one night for some NSA fun. The sex is so hot, they accidentally fall in love. They’re both as pretty as they are restless so it’s a surprise to both of them that their one-night stand turns into a live-in relationship. This is unfamiliar territory amid their hookup culture and they have to invent games and rules to keep things interesting, but connecting is actually refreshing, and they’re intoxicated with that first blush of love. But as the newness fades, the lengths they’ll go to to keep things spicy become extreme.

Open relationships are not for everyone. I’m pretty okay about anything consensual that makes people happy and fulfilled, but let’s be honest: open relationships are hard to

maintain. Also true: monogamous relationships are hard to maintain. Half of those end in divorce. Some people think they can solve the challenges of monogamy with polyamory and perhaps some are right. But if it’s difficult to make one person happy, it’s much harder juggling two or more.

Gabi and Martin are of a generation needing constant stimulus and feedback. They’ve gone from a phone full of potential lovers to one, single lover, night after night. At first it’s exhilarating to fall head over heels, but eventually monogamy starts to feel constrictive. Relying solely on each other to have their needs met becomes “boring.” So they open things up. Soon they’re swiping left and right harder than they ever did before. Does this save their relationship, or does a certain ugly green monster pay them a visit?

Laia Costa and Nicholas Hoult slide into their roles effortlessly. The camera is penetrating, the script languid. We get sucked down the rabbit hole of their relationship along with them. And you know what? Down there, it looks exactly the same as all relationships from the beginning of time. And it’s kind of dull. Director Drake Doremus doesn’t really have anything new to say. You don’t so much root for the characters as you root for their mistakes to catch up with them. Which is probably quite a bad sign, in retrospect.
