The positives for me:
Great OSTs.
The cinematography, except the last EP, was also good. Although some transitions from the island and the city settings are sometime abrupt and are jarring to the viewers, the used of flashbacks in the last episode left a bitter aftertaste for my viewing experience.
The acting was meh for me. It was there but sometimes it borders into silliness, especially the comedic ones, that causes me to skip some scenes.
Storyline: this series had the potential to be a good one but sadly it did not deliver. I enjoy slow burn storylines like of this one, but too few episodes of this series did not flesh-out the characters for me. Maybe too many pairings and arche of the minor characters killed the development of the mains. This was obvious by the last episode. the writer/director tried to tie up all premise they had presented from episodes 1-5 within a short period of viewing time leading to a confusing, lack-luster ending.
I wish they could have made it longer with few side stories and with focus to the main characters. I mean ep1-5 didn’t even explore how Sun and Arthit develop feelings for each other.
Rewatch Value: I can watch Boun x Prem storyline in repeat but will probably skip many scenes.
