Ok, so season 1 is great, excellent. The writing, the ACTING (the cast is all stars and it truly shows, they are all superb). There are some very touching moments in the sessions with the therapist, and the "mystery" is compelling. Subtle characterization, like the phone calls between Heidi and her boss. 5 stars!But Season 2... is a mess; the tone changes very much (less suspence, less psychological games, more "action", there's even some humor that to be honest is not all that bad), I've been listening because up to a point it is somewhat interesting to see where the story goes, but it all crumbles down in the last 2-3 episodes that become quite implausible. Unfortunately compared to the expectations set by season 1 it's a huge disappointment and, if you don't mind a "downer" and quite a depressing (but in my opinion more fitting with the tone of the show) ending, I suggest that you stop at the end of season 1.
