Sadler, who has been very open about her own mental health struggles, including her suicide attempts, has said that much of the show comes from her “lived-in experience.” The ability to find humor in pain is a gift. The onscreen rapport between the three women is terrific, and the fierce love/hate dynamic between the real-life siblings is palpably relatable.

Sadler’s performance has an undercurrent that is so loveable that you can’t help but root for her. “I met the love of my life tonight . . . What should I do? Probably just leave it, right?” she asks her sister after meeting someone she’s instantly attracted to. So damaged are these women that normal signs of affection, like a father hugging his daughter goodnight, is viewed as deviant. 

Comparisons to the similar in tone beloved British comedies Fleabag and Catastrophe are right there for the taking, but in an odd way, the show reminded me of Seinfeld, where the characters, who behave fairly horribly, don’t grow, change, or learn anything from their repeated mistakes. Billie describes the family motto as “death, silence, hate.” That’s where they start, and that’s where they end for the most part.

The title of the show, which premiered last month on BBC 3, comes from the ever-naive Dev, who declares Josie and Billie to be “so brave.” But brave also describes a show so willing to confront mental illness and toxic dysfunction in such a non-politically correct way. The way the comedy confronts topics including eating disorders, abortion, and drug use is also brave. Such Brave Girls will leave you rattled and off-kilter. But it will also, maybe to your utter surprise, leave you wanting more.

All episodes of Such Brave Girls are streaming on Hulu.
