Been catching up on it, seen the first three.
Brilliantly acted but terribly written, I feel. Characters are introduced almost in the same scene that terrible things happen to them, which gives no chance to build empathy or provide us with a reason to care. It crosses into eyerolling melodrama too much, with the SAD being overplayed -- none of those people have *anything* good in their lives. It's incredibly bitty, with segments of story suddenly being levered in and then thrown away again, with no purpose or direction for it. And the worst crime of all in drama -- all this piecemeal story with characters we have been given no reason to care about makes it dull, dull, dull.
I'll stick it out, having invested the time in the first three of six. Maybe the second half will improve. Even if so, however, that doesn't excuse the poor drama-by-numbers nature of the first half.
