I thought this book was very slow at the beginning, and then picked up around the middle, until I was racing along to the end. The characters are, overall, more sympathetic than in "Gone Girl," although I'm not sure I liked it any more than that book. It's definitely intriguing and the characters are all messy, imperfect people.

I agree with people who are questioning the casting of Emily Blunt as Rachel--yes, she's British, but does she really sound anything like the way Rachel is described? Especially because Rachel's appearance is frequently referred to.
