Whitney Cummings is best known for her raunchily commendable work as a Comedy Central Roast Mistress. Here she makes her directorial debut, paired opposite Sofia Vergara, for an occasionally amusing look at the science behind our romantic fluffs. Through with romance, a nerdy neuroscientist (Cummings) with a minor in clairvoyance dreams of reading her patient’s minds. Her reasoning that a lot of couple’s problems have a biological basis acts as an excuse to bypass storytelling: instead the film fashions a series of sequences — separated by algorithm chart-chapter stops and Cummings’ voice over — explaining how and why her characters think the way they do. Like so many comics who make the move to behind the camera, the visuals take a back seat to dialogue and performance; Cummings and Co. don’t simply cover old ground, they reupholster it. What is relatively fresh — boy catches girl masturbating to porn — is given an intensely unenthusiastic presentment. And with a title such as this, the script could have used more smarts. Still, any film with both Beanie Feldstein and Will Sasso is worth a look. (2017) — Scott Marks
