Those of us who like psychological thrillers enjoyed this series. Those who don't like this series seemed to want a fairy tale ending. This is not a love story. This series is about obsession. I haven't read the book, but now I want to read it. The only thing I did not like was Louise's continuous poor choices. She got too involved in the couples lives.
Sidenote: I wonder if Rob can't go back to the Adele's home because he's afraid that the real Adele's spirit will be there. And I am still wondering how David "happened" to be driving past Adele's home when it caught fire.
