This is a "full disclosure, I've seen the movie twice" review, although it's been at least 5 years since I saw the movie and some details were fuzzy. That said, mild spoilers ahead.

Something about the book just didn't quite land for me. I usually enjoy rereading thrillers to spot clues and such and was really excited to do so here. But I mostly just found myself saying "...really?" at most parts. I guess what I'm getting is that I was expecting more payoff (more cleverness?).

I feel bad because I really wanted to like the book and, to give it credit, it's very readable. You'll turn pages quickly and most likely enjoy the ride. Recommended if you're into unreliable narrators, but you may want to skip this one if you're familiar with the plot.
