It’s also a glimpse into Sadler’s mind, where the show’s insular nature works in its favor. There’s nothing braver than baring your darkest thoughts and trying to laugh at them — and nothing better than a sister, a mother, or an audience accepting you just the same afterward.

There are still lots of places for Such Brave Girls to grow, emotional gaps for it to fill in and realizations for it to force upon its unwilling characters. But for these six episodes, it works as an introduction to a lethally droll and riotously depressing family and a promising new comic voice in Kat Sadler.

Such Brave Girls is indeed brave – singular, fresh, scabrous and unflinching – but still – or, rather, as a result – hilarious. Let’s hope a second series, set up by the finale, will, like the girls, eventually make it through.

Such Brave Girls could be a little funnier than it is, but the three main characters have such well-defined personality quirks that seeing them interact with each other and the world around them is pretty entertaining.

At times, the acting and plotting verge on basic, but Sadler, Davidson and Brealey truly spark together. The more you watch, the funnier, stranger and more original it starts to feel.

The show has "cult hit" written all over it. Which means it is not for everyone. But anything really funny isn't, because some people are going to find it isn't funny at all.

I hated the first episode because it’s trying far too hard, and the sisters talk about their mental health with the relentlessness of, well, young people these days who talk about their mental health. But over the course of a few episodes it grew on me a bit, because Sadler – who has said the series was inspired by her own breakdown – sends up this self-absorption.
