Jacob Gehman’s review published on Letterboxd:
An almost-really-good noir-esque look at someone getting in over their head, using the seedy boxing and crime environment. Killer's Kiss is a very capable film, though certainly is a "lesser Kubrick". But considering how early it happened in his career, it is hard to fault the film for certain short-comings. The obvious audience for Killer's Kiss is Kubrick aficionados, however, I think it is solid enough without even knowing the Kubrick connection to be enjoyable by fans of more obscure noir cinema.
