When I heard about THE POLICEMAN'S LINEAGE, another undercover cop drama from South Korea, I expected a lot. The country has a fine history of making compelling and exciting genre films and I hoped this would offer more of the same. Sadly, the end result is a distinctly average production that never really gets off the ground, despite the usual sterling production values and attention to detail. The hero, played by the kid from PARASITE, is sent in undercover to investigate a corrupt cop and his buddies, and the story develops from there. The usual shades-of-grey characters are interesting but the film never really thrilled me in the way I hoped it would. Instead I was left thinking, so what?
