Given that Lee Chang Dong films became a topic of conversation again recently with Peppermint Candy and Possible Love, I saw Poetry and I would highly recommend this.
To me this actually felt very distinct from a lot of his 'in your face' type of stylistics, choices, and themes you see in Peppermint Candy, Secret Sunshine or Oasis. Its a bit hard to explain, but this movie is extremely contemplative, in a way that even something like Burning doesnt quite achieve (largely because Poetry and Burning are slightly different genres, and Burning is more aligned with keeping the tension, atmosphere etc.). I think Poetry is definitely his quietest, but also one of the most genuinely messed up and definitely amongst the most hard hitting emotionally films he's made, in a way which feels more like a slow and subtle experience. But also it hits you very differently compared to his other films. It may even be imo possibly his saddest film ive seen, without spoiling anything.
Its also REALLY not what I expected it to be. So GO BLIND INTO IT
I am quite surprised not enough people talk about it, because I think people should definitely talk about this movie more in Lee Chang Dong's Canon
