matt lynch’s review published on Letterboxd:
The little girl with leukemia, the prison guard on the take, the gang boss who needs a heart transplant, the detective reckless with his men's lives, and his man on the inside, destroyed by addiction and conflicted loyalty. All of these are literally or figuratively parts of bodies in open revolt against themselves, every system is in some way corrupted. Not that this gets weighed down by subtext...never once does it forget that bodies are also weapons, and it spares very few ways for them to smash, shred, and puncture each other, piling one bonkers setpiece on top of another, with a lithe, floating camera disrupted with quick but deliberate cuts and blisteringly fast choreography. One of the best HK action films in ages.
