Nev @ LFF’s review published on Letterboxd:
This hyperbolically titled Norwegian romance will steal your heart and then tear it in two. Balancing heartbreak and humour, The Worst Person in the World is a millennial love triangle fronted by a fickle female lured by two respectively dashing love interests.
There are charming traits to be found in each corner of this love triangle (including its naturally flawed protagonist), but what started so breezily and quirkily, ended up becoming frustratingly cold, self-destructive, and with little resonance. I genuinely liked that the film sought to challenge the taboos of sexual discourse early on, but the sex itself seemed somewhat unnecessary. Within the story, there’s some meaningful discussion about mixed-age relationships though and the expectations of coupling up.
It is a good performance from Renate Reinsve and the film is at its best when it steps out of the ordinary into something more surreal. The time-freeze scene is a truly heartening highlight, while the comparatively dark, drug-induced hallucinatory sequence impresses also. The first half of the film is indeed better than the second, but when the script is funny, it’s really funny, with the film’s best laugh coming from a wittily worded gag on “womansplaining”.
