I really enjoyed the first season, but the second season is just non-sensical. Such sloppy writing - people and things just appearing and disappearing, for no discernible reason, because they're messing with time - and so I suppose the writers thought they could get away with it. It's just lazy, stupid, and very dull by the end. Hugely frustrating because the ideas behind and execution of season 1 were really good. I changed my rating from 10 ( following season 1) to 5 (because season 2 was such a turkey).
