Season 1 was a nuanced psychological thriller with a fantastic resolution. So far season 2 is a soap opera. A shame, I was looking forward to seeing Michael Ealy, the one season wonder, again.
In season 1 there was palpable tension between the lead suspect and the lead investigator, to the point you weren't sure which was the bad guy. The tension in the community, the actions of the media, the dubious motives of others surrounding the main suspect created a genuine tension right to the very end.
Season 2 is sensationalist, lacks any genuine tension and revolves around soap-opera style revelations. After 7 episodes I don't think I really care anymore who the murder is.
