The Love of Siam / Rak Haeng Siam (2007)
This is a really emotional movie and even though the film has something about 3 hours, there was no single part that woud make me bored.
I definitely recommend you to watch it. I think it’s very romantic (and there didn’t have to be any sex scene to make it like that.) I was crying really much but I was kind of disappointed of the open ending (just because I just don’t like them.) But even after this type of end, it’s a really MUST to see this beautiful film with great (and symphatic) actors.
