I didn't know what to expect before watching the movie, the plot was very short, and I wasn't aware that it was inspired by two others movie. However, I can say I was agreeably surprised!!
The first part is well done and interesting, and put the frame of a complex discussion about important matters following the relationship between the two protagonists : family and society acceptance, friendship, choices in life... I really like this part that is heavy emotionally but also portray the innocence of youth and love in a pure way (yes, we are not all crooked, delinquents, perverts etc...).
The second part is quite special. I can see why many people don't like it : it's complex. However, I find it really well done and very interesting. I was very surprised !! You might have to use your brain to understand the all thing (but it's not complicated). Obviously, many didn't want to try to understand and it sadden me because the plot is very interesting and special for a Thai movie where it's usually cliché (even if I like it when things are ending well).
I enjoyed the movie so much. I really recommend it. At least give it a try! Even if you don't like it or don't understand the story it won't be a waste of time because : the actors are GOOD, there is a beautiful ambiance, beautiful landscapes, beautiful scenes... it will make you think about many things your life.
