No good will come of this.
CW: sexual assault
Emerald Fennel delivers perhaps the most #MeToo movie I'm aware of and it's a tough watch, as you'd expect, but lightened by the appearance of Bo Burnham as a genuine romantic interest for Cassie.
Mulligan is fantastic and inhabits Cassie's broken soul perfectly. As you can imagine things don't go well but there's a certain element of wish-fulfilment about it not going terribly wrong sooner. It's a kind of feminist revenge superhero story.
Where it is less satisfying is in its living up to the stereotype the manosphere would paint of it, which I think lets it down. You could, in good faith, level an accusation of misandry at this.
Nonetheless 8/10 highly recommended.
