I'm enjoying Part Time. Real character development, so it may seem slow, but I'm emotionally invested in all the characters.
I'm watching Kiss and I can see the sole fault in SOTUS, which is not really major. Kiss managed to make the secondary characters just that: secondary. They are not important at all. I'm not wondering what Pete's and Kao's relationship is, nor am I wondering what June is doing off screen.
SOTUS made you care about the secondary stories like May and Em, although they got so little screen time. Wad and Prem too, although they got no development. In fact Wad seemed to have been forgotten totally!
Yet SOTUS is among the best Asian and, arguably, the best Thai so far! Its nearest competition IMHO was Hormones.
I hope to see N'Singto and N'Krist in other projects. They are both really amazing actors. Probably the best Thailand has to offer!
