The reviews lean clearly positive, and they agree on what the film is: a tightly built thriller that is funnier than most of its kind. Most critics praise the control of the filmmaking, the dark humour threaded through the carnage and the inventiveness of the set pieces, with the body-disposal sequence singled out more than once. Lee Sun-kyun’s performance draws near-unanimous praise, several critics noting how his frozen, physically reactive panic stops the comedy from floating free of the stakes.
The reservations cluster on depth. Variety finds the characterisation shallow and the hero oddly free of remorse; The Playlist and The Hollywood Reporter enjoy it while allowing that it does not mean much. Vulture is alone in finding the second half less exciting than the first. The spread is narrow, running from warm to warmer, though three of the eight reviews could not be read in full, so the picture rests on five.
