This series has a madcap quality to it, so although there are some intense scenes there's an outrageousness to the whole enterprise that takes the edge off. You might even find yourself chuckling here and there.

All of the scene-chewing comes from the two adult leads and the student ringleader of the little gang of nasties in the classroom. This is a decidedly evil bunch of kids -- by the end of the series most of them have attempted murder -- but in accordance with the wacky rules of Asian drama and this series in particular, none of them has to account for their crimes, and in fact by the end we are meant to sympathize with them. (They are even forgiven by their chief victim, who sincerely tells them that he loves them.)

In addition there are jaw-dropping plot developments that I haven't even hinted at. You will have to watch the series to experience them -- and I do recommend that you do that, although I caution fans of hardcore thrillers that most of what you see is so over the top that it's hard to take seriously.

As entertainment, though, this series does the job and will keep you watching. I binged it in one afternoon. In my book that deserves an automatic 8/10.
