Honestly I thought the story was too thin even for a feature length movie... It has been a long time since I watched it but I remember that I more or less guessed where it was headed by the end of the first act and then the rest was kinda boring waiting for it all to unfold. I have a hard time seeing how this depressing story that hinges almost entirely on one twist will work as a multi-episode series.

Maybe there's more to the book though.
