Gone Girl
I read the book a couple of years ago and I have never been this impressed with a book to movie adaptation in my life. Of course, most of the credit goes to Gillian Flynn being the genius she is and the casting of Rosamund Pike. I also surprisingly loved Ben Affleck. But I think that is mainly because he's had a lot of practice in a decades long toxic relationship with J-Lo so it probably taught him a thing or two about psychological warfare. Some details were overlooked and changed but thats to be expected but the butchering of the 'Cool Girl' speech pissed me off.
