More shallow than a kiddie pool.

I was really sad, I had been excited when the series was announced, I was sad when I saw the trailer because I hated it, I got excited when I saw comments praising the series and got sad again when I decided to watch it. Although the cast holds up well with great performances (especially First, Neo, Khao and Louis) they have no content, no script to hold on to. To quote a webdiva here in my country: "The script? What script?", the series tries, really tries, to pass a political and social message against oppression and in favor of the weakest, but it can't sustain itself for more than 10 minutes without putting a bad text or a nonsense scene, they try to give artistic credibility by including (the most basic possible example) George Orwell's book "1984" and fail miserably.
I believed that at least the romantic scenes would be able to save the series, but they didn't manage to do that either, the couples (who have great chemistry at least) seem to be more friends trying out silly games of holding hands and kissing each other's cheeks than real couples, the series presents once in a while a scene with decent and cute content from the couples but nothing beyond that.
I thought that in the last episode at least they would get something right, but they didn't. Many plot points that could have been used throughout the series to make it stronger were thrown in the last episode just to try to close everything with a perfect knot, but a spoiler: the knot got loose.
I hope that in the future GMMTV gets it right and manages to turn FirstKhao into a series that actually has a script.

Final rating: 4 because the kissing made me happy (sometimes)
