In all honesty, it wasn't that good.
(A) The PLOT, the idea, wasn't bad at all. I hate sad endings that are usually associated with paranormal/supernatural love stories, so I really liked the early twist (ML was comatose, not dead) which lead me to believe there would be a happy ending.
(B) Too many characters, too many sub-plots. There's no need for that. Some support characters really didn't need that much screen time.
(C) The ACTING was pretty much amateur. The characters were most of the time either not emotionally invested or overreacting to everything and anything (think "extra", like really extra!). I would usually blame to the young age, but this is not the case. The coaches (all of them) were specially bad, and the Director was borderline campy. The guy playing "Jedi" (Oat Pasakorn Sanrattana) was the only one who seemed more natural, which is sad, because is the ML who has the least amount of time on screen.
(D) The AUDIO was terrible sometimes, and the english SUBTITLES (Line TV) even worse.

It was an OK show. I think the same story could easily be told in 7 or 8 episodes.
