Same series, just different story. They are going on a completely different story line. Dont think of the show as a linear plot line, but more like an anthology.
K, I hated on this show first season, because I was thinking "how do they continue the story for season 2?" so I didn't bother to watch more than half an episode. Nice originality to this series, but still too creepy for me to watch.
Faster start, yes. It just seems very random so far. I guess that is what you are talking about with the stories unfolding. I'm sure I will come around in another couple of episodes.
