I loved the book but thought the movie was okay. The story line for the movie was very true to the book. Also the book was so dark but I thought the movie had oddly placed humor.
I love, love, loved them both. It's been a while since I read the book, so I feel like I should go back and refresh my memory, but I know they did a darn good job of staying true to it, probably because of Gillian Flynn doing the screen play. I can't wait to see what they do with her other 2 adaptations!
I saw the movie without reading the book. It was definitely interesting, but it kind of rambled, I thought. And I didn't like the ending, which is funny because I often write open-ended fiction myself. Got a taste of my own medicine!
