I rarely find a film I can get so caught up in anymore, I'm usually stuck knit-picking at the smallest of issues like lighting or sound but literally everything was perfection. I could literally write an entire book on why this film was a masterpiece and how much thought the director had put into each detail and scene. From the connection to the things teenagers like to the biggest of problems they can face. The entire film was about pushing the boundaries of korean morals and how young adults who have gone through trauma can react to certain situations. You literally need to watch it at least four times putting yourself into each of the four main characters shoes and even then you'd have to watch it a fifth time to connect all of the pieces! It's so brilliantly put together and the ending was amazing. Usually films aim for a big ending, a happily ever after or a cliff hanger but that ending really brought the idea that it was meant to represent life and how sometimes you don't get a happy ending.
