Saw this film at Cannes Film Festival this year - and what started as a film just to fill in my free time slot turned out to be the best film that I saw at Cannes this year! (And I did watch Lanthimos' 'Kinds of Kindness' and Paul Schrader's 'Oh Canada!'.) This film had everything that a good film should have - great acting, good plot, insane comedy, beautiful action sequences, all with a great pacing and comedic timing. The film was subtitled, of course, but the entire hall was cracking up in laughter the entire time and clapped wholeheartedly as the film ended. The film follows a team of special case investigators within the police department of Korea that are investigating a serial killer with a unique modus operandi. You'd normally expect the film to be grim and disturbing, but you'll be surprised at how easy and comedic all those scenes were. Do give it a shot!
