Cooper & Hizli's darkly twisted comedy about a toxic friendship, a toxic marriage and toxic secrets is an inconsistent beast and does not always hit the right mark - but a fantastic cast (particularly national-treasure-in-waiting Lenny Rush and the brilliantly unpleasant Dustin Demri-Burns) anchored by the two writer's own magnetic presence and some smart unfolding mysteries keeps it very watchable throughout. Where the series can go from here is an intriguing prospect because it's hard to argue with accusations that it didn't quite tie everything (or, indeed, anything) up by the last episode.
