If you were lucky enough to see Australian comedian Hannah Gadsby live last year, you'll know exactly what to expect from Nanette (Netflix). This is a live recording of the show with which she won the Barry Award at the Melbourne Comedy Festival and the best comedy show award in Edinburgh (shared with English comic John Robins).

And if you didn't see it live, you're in for a treat.

Well, maybe treat is the wrong word. What you're actually in for is a harangue, a confession, an accusation, a treatise on art history, an interrogation of the dynamics and limitations of stand-up comedy and, finally, a kind of catharsis. It's brilliant and exhausting and when it's all over you'll probably feel the need for a Bex and a good lie down.

I don't want to reveal too much of the narrative – for this is a story rather than a string of jokes, as Gadsby herself reminds us more than once – but it takes us from her difficult childhood in rural Tasmania to her decision, allegedly genuine (we will see), to quit stand-up comedy because of the psychological damage it does her.
