Overall it was a very intriguing and suspenseful series with many twists and turns. The visuals were very good, the acting engaging and the story kept me guessing.
I have one nitpick with the TV series. In the scene where Harry and Marcus are in the bar and Harry is giving Marcus advice on writing (a scene which is repeated on the tape over and over again), Harry describes keeping the reader on edge and in suspense using the word "tenderhooks" when he means "tenterhooks." I noticed it immediately and might have just let it go but it was repeated over and over again! Not one person involved in the show knew it was the wrong pronunciation and thus the wrong word? There's no such thing as tenderhooks! The characters are supposed to be well-educated writers who would know the term so it compromises the credibility of the characters when you get that wrong.
