Documentary Decision To Leave is Park Chan-wook's first film in six years.
Romantic noir is an oddly quiet detective drama with occasional outbursts of violence.
Two lead characters are unable to free themselves of the memory of each other, and betray, mislead and hurt each other.
In Decision To Leave, Hae-jun (Yoo Seung-mok) becomes infatuated with the mysterious Song Seo-rae.
His obsession clouds his job, makes his sleep even more interrupted and destroys his home life.
The film leaves you second-guessing and questioning plot points and little moments.
The film is directed by Park Chan-wook and stars Jung Hoon-hee, who won Best Director at Cannes earlier this year.
The fog shrouds the storyline here, but makes it all the more intriguing and addictive.
