Yes, I am watching it too. Talk about TAUT drama! It is intense psychologically.
I watched the first season onDemand before season II started.
I am hoping Sarah gets settled though, her dragging her poor son around is starting to bother me.

And the paranoia factor is getting intense! Is someone after Sarah?
I think Rosie's mother's behavior is rather over the top. It resembles more guilt than grief. Remember when her sister asked her..."why didn't you call Rosie that weekend you were camping?" Was the camping trip a planned alibi? I wonder if there was father/daughter incest going on she suspected? Lots of these mystery shows turn incest up as motives in the end.
I thought the Dad could have been involved...the way he showed up when the body was found, was very hinky to begin with. Perhaps, the Polish mafia killed her to bring HIM back to work for them? But you know, I've been all over the place with that show... everyone seems guilty at one point, and then the story turns, and another seems guilty etc. I went to bed early last night, so I will watch it onDemand today.
