10 Movie Endings You Can Only Work Out For Yourself
4. Burning
Lee Chang-dong's mesmerising thriller Burning follows a young man, Jong-su (Yoo Ah-in), who runs into a childhood friend, Hae-mi (Jeon Jong-seo), with whom he becomes infatuated.
Hae-mi soon enough heads off on a trip and returns with Ben (Steven Yeun), a man she met on her journey, an initially affable yet mysterious man who may or may not harbour a dark secret.
Ben eventually confides in Jong-su that he periodically burns down abandoned greenhouses in order to feel alive, with the implication being that Ben may or may not be using "burning greenhouses" as a euphemism for murdering young, lonely women.
Thereafter Hae-mi goes missing and Jong-su comes to believe that Ben is the culprit, resulting in him murdering Ben at the very end of the movie.
And yet, Chang-dong never commits to Ben's potential guilt one way or another, leaving the matter teetering so brilliantly on a razor's edge.
Audiences are free to read into Ben's apparent euphemism and his possibly sociopathic tells - like yawning while in social settings, because he's secretly bored of all the normality - or not.
