I'm only thru the 1st 3 episodes but I'm enjoying it so far. Slightly different premise from other series I've watched in the same genre. It's entertaining and "spooky" without being horrifying (which I don't care for). Decent special effects.
The characters are each unique in their own way which rounds out the team well. There is one basic story for each episode with underlying stories that continues thru all episodes. I wouldn't suggest skipping an episode or watching out of order. I feel you'd miss an aspect of character development if that's important to you.
I did not know this was a book series. It wouldn't matter to me as I find the series entertaining without any preconceived ideas.
