I have read both of the books that this show is based on by Tana French.
In The Woods and Likeness.
Tana French's series Dublin Murders are exceptional murder mysteries with excellently detailed characters.
I feel this tv series failed terribly. I don't understand why the producers felt it would be okay to combine two completely different stories into one. You are speeding through both stories and leaving out some of the best parts in each book. The two stories do not belong together. For those of us who have read both books, this tv series makes no sense.
