The first time I watched the movie it felt a little lengthy and the acting a little stiff.

Nevertheless I have watched the second part (see my review there) and thought, I should rewatch the first one because I felt so much closer to the actors in the second movie.
And I am glad I did so. Because now, with the feelings from the second movie, the acting in this movie makes more sense to me. The english parts are still a bit bumpy, but Tonawanik Adisorn plays the "being torn because of having had sex with a man" really good, the confusion is literally writen all over his face. He is a quiet character and I misread that the first time, so you have to watch his face closely. And his heartbreak brought me to tears (again).
The character of Oat is even when rewatching a bit plain, no changes there. But Yumi is great, I loved her from the beginning.

Another thing I love about the movie: the soundtrack. There is not much music, but the song when they kiss is terrific and adds to the scene extremly well. And the scenery is awesome, for example the picture when they stand on the mountain and watch the land below is like a painting, beautifull.

My conclusion: I like the movie *insertsmileyhere*
