The dramatic-sounding title "Zero Hour" is actually a translation of the Hebrew term for the time before first period at high school. Still, it's a nice dramatic title that could fit half the dramas on TV today, certainly including this one.
From a delicate situation exploring what the proper boundaries are for classroom debate (and for the teacher's guidance of it), the series swings into an exploration of the viral video culture and the polarization of activists, and meanwhile-- because, after all, it is a drama with characters-- there are various family tensions relevant and irrelevant.
As the series progresses, it turns out that the family side of the plot and the characterization side of the script aren't just devices to prop up interest in the social issues that the characters face. The male protagonist in particular sees a lot of complexity in the mirror-- more than he can easily handle-- and some other major roles also turn out to be more than cardboard.
It all comes to a dramatically satisfying ending. So much so that I'm kind of worried lest somebody try to tack on a second season.
