I watched the drama version first before watching this movie. And for me, the movie is dissapointing. If you watched it first without watching the drama or reading the novel, maybe it's still a passable movie. But after watching the drama, the movie felt less complete. It can also be because of the drama is so good that I feel the movie kinda destroyed it (?). The story just jump here and there and miss a lot of important stuff. The ending is also very weird and unsatisfying. But the story still mantain its main storyline of how it is supposed to be. Except with uncomplete storyline. But, that's how I feel. No pressure.
