I really loved it! It kept my attention fairly easily and we watched all 4 episodes in one sitting when we couldn't sleep one night. I watch so many shows and am always, always disappointed with their endings and feel somewhat robbed of the time I have easy d getting to that end point........most definitely not the case with this one and it kept me guessing right up to the very very end.
Like I said don't understand the bad reviews so I am glad I ignored them and made my own opinion.
Not read the book but think it's appeared in my kindle suggestions list on occasion and I liked the idea of the storyline. Now I've watched the TV version I doubt I'd bother with the book now however.
