Don't listen to the other idiot reviews by kids and teenagers watching this film for their celebrity idol's cameo. Don't get me wrong, IU is great in this film (she's always a great actress) and her cameo is so well done. Nothing against her, only her idiot fans giving this movie a bad review. Director Jong-kwan Kim is a master at his craft reminiscent of the great Japanese master Yasujiro Ozu with his long takes and idyllic shots. As other great reviewers have said about this film, this is a meditation on loss and mortality, deeply felt and poignant. A more mature and slice of life film, not for kids with low attention spans who can't appreciate real art.
