Love how this explicitly references The Man From Nowhere. The Killer is familiar but it knows exactly what it is, it gets in, delivers slick action sequences that are coherent but continuously kinetic and brutal, and gets out in a little over 90 minutes. Speed-ramping tends to annoy me, but it's well placed here. Tactically deployed, the speed-ramping accentuates the speed, precision, and power of our main protagonist as he makes his way through a sea of baddies. He is a stoic agent of punitive justice against the darkness that permeates our modern world. A simple story of good vs evil, there is no grayness here. Jang Hyuk plays the part well, oozing understated confidence amongst the carnage to suggest that he has been here before and everything will be okay.
Love of all things cinema brought me here.
