I really enjoyed the book and found the film to be disappointing. Visually the thing is interesting and the interaction of the characters and dialog is pretty good, in fact, I recognized a decent amount of the dialog from the book.

But this film lacks the suspense of the book, it kind of plods along until it reaches the end. There are a couple big plot twists in the book and they are there in the movie, but they’re really easy to miss. When the end comes, it feels important but I don’t think it’s entirely clear why.
