I just finished episode 6 and I'm annoyed more than anything. Annoyed that I've already invested 6 hours. Annoyed that I will probably watch episode 7 just because I'm a completist. Annoyed that the entire 6th episode was nothing more than a fever induced nightmarish waste of time that did nothing to move the story forward.
I'm a huge Natalie Portman fan, but her character in this series is so unlikable, it's hard to care about what happens. If you're on the fence about starting this series, save your time.
I haven't read the book, so I can't speak to how well the storyline was followed, or whether the book would be aa annoying to read as this is to watch.
