This super-taut and lightning-fast action flick from South Korea is a worthy complement to ‘John Wick’, starring Jeon Jong-seo as a one-woman killing machine out to avenge the death of her best friend. Director Lee Chung-hyun has put together a present-day feast of eye and mind candy with a slick, updated ‘Miami Vice’ feel. It’s loaded with snazzy visuals, a thumping soundtrack, and performances that draw you in from the first frames. A hyper-violent neon thrill ride, the film is a virtual must-see for fans of the genre. Don’t sleep on this one.
