Sally Jane Black’s review published on Letterboxd:
What could potentially serve as a critique of the serial killer genre, if albeit not a particularly useful one, is soured and defeated by Von Trier's misanthropic worldview and the manner in which the film acts critical of serial killer misogyny while reveling in it. They point out Jack's sexist point of view while going back to the violent deaths of women over and over, emphasizing the grotesque removal of a woman's breasts as an act of sexualized murder, and the general nihilistic perspective of the film. Add to that several moments of anti-communist imagery, and it's precisely made to piss me off. If I had realized this was Von Trier before I put it on, I wouldn't have watched. But here we are, a lifetime later, on the other side of this pretentious, smug arthouse-edgy bullshit.
Edit to add: I forgot to mention that the song used over the ending is just fucking lazy filmmaking and not the clever punchline Von Trier wants it to be.
