If the rom-com is dead, no one told FX, creator Stephen Falk (who came up through OITNB creator Jenji Kohan’s “Weeds,” a show we should probably be catching up on, between the two of them) and the cast and crew of “You’re The Worst,” the most refreshingly acerbic, deceptively sweet screen love story in quite a while. The premise is simple: Chris Geere’s Jimmy, an ex-pat British novelist, is the worst: a misanthropic, amoral, borderline alcoholic, foot-fetishist and compulsive masturbator. Aya Cash’s Gretchen is also the worst: a coke-snorting, rich-kid music publicist who doesn’t so much have intimacy issues as much as a straight up phobia. They hook up at a wedding from which they’ve both been ejected, and against both their best instincts and the horror of their friends, somehow fall into a relationship, despite both being deeply opposed to such a thing. More authentic than most at depicting love & sex in the Tinder age, where no one’s dating and everyone’s ‘hanging out’ (the great Onion headline of ‘Fuck-Buddy Becomes Fuck-Fiancé’ comes to mind), it’s sharply written and frequently laugh-out-loud funny, but in part thanks to the great performances by Geere and Cash, lets us see our anti-heroes as the vulnerable, damaged people they really are, and they prove far more rootable-for as a result. Add in a selection of ingenious supporting players, most notably Desmin Borges’ PTSD-suffering vet and Kether Donahue’s hottest-mess as their best pals, and we couldn’t be happier that an extended second season is landing in the fall.
