This is another case of a movie with so many other elements and references to other movies (The Terminator, The Matrix, John Wick) that there’s no room for the film to make its own identity.
The movie borrows heavily from The Terminator in that a character named John Smith (don’t trust anyone with that name!) seems to be charged with saving the heroine from the Hitman who wants to wipe her out.
In fact, the first 20 minutes (or so) work as an homage to The Terminator , with the seemingly indestructible 47 carving a swath of death and destruction to get to Katia and John.
Consequently, its tale often feels like some sort of new-world reimagining of The Terminator, with Agent 47 as the mecha-killer and Katia as the Linda Hamilton-esque badass who must struggle to understand her circumstances (laughable hint: her full name, Katia van Dees, is “90” in French) while teaching her preprogrammed compatriot to be less of an inhuman monster and more of a kindler, gentler killing machine.
The movie tries to pull off the transition from The Terminator to Terminator 2 in a single film, by positioning Agent 47 as a force of malevolence before teaming him up with Katia, whereupon he becomes a force of, if not exactly good, then perhaps a sort of neutrality.
It’s basically The Terminator, if the plot was a baffling mess, none of the human characters were even remotely interesting, the heroes and villains switched allegiances constantly for no reason, and the entire script sounded like it was cut and pasted from a list of the most clichéd lines of dialogue in Hollywood history.
