Acting: Seo Kang Joon as Jin Ho was excellent. He didn't say much, but then he doesn't have to. He just has to BE. What he said in the voice overs was beautiful, but I kept wondering why he never verbalized any of his thoughts. Park Min Young as Hae Won - in my opinion, she can do no wrong, she's that good in everything she does. However -
Characters: Jin Ho kept everything bottled up inside. Hae Won reminded me of Eeyore, she was so morose all the time. There were some other interesting characters in this show as well. I loved the scenes with the book club meetings.
Music: The music was wonderful and went perfectly with the show.
Cinematography: There is no question that this show was beautifully filmed. The camera angles, the scenes in nature, the close ups.
Story: Here's where it goes wrong for me. The story itself might have been really good, but this was one of the slowest shows I've ever seen. I like a good story as much as the next person, but when you show scenes again and again of making coffee and tea (are we in a Folger's commercial?) or take five minutes showing the female lead walking up a road dragging her suitcase behind her, that's just too tedious for me. There was so much quietness in this that I felt like no one was talking to each other.
I would, however, say to give it a try for yourself, since I am definitely in the minority on this one.
