First off, I think the show's production quality and acting are superb, just for that I recommend giving it a try.

Secondly, this show really should have a fantasy as a genre in the title.

The first 2 episodes were great they had me at the edge of the seat trying to figure this stuff out that was going on. After that the show fell off for me since they introduced supernatural elements to it. There is no point in police investigation really if you are just left guessing since it's a fantasy and they can come up with whatever explanation. I watched till the 5th episode.

I had no clue it was based on a Stephen King's book, then I would have known it was going to include supernatural elements.
