It seems like a cliche plot, wherein the guy is madly in love with his ex-wife and his new wife is just a surrogate. And the new wife has to fill in the spots of the old. But as the movie progresses it turns into something completely unexpected and different. Never would I have thought the ending would be, when I started watching it. It's not a horror movie, but it's one worth watching for the thrill. Lily James showed some amazing skills and it was very easy to fall in love with her. Armie Hammer depicted the sad husband role to an amazing perfection and suddenly the turn in his character was the unexpected part of the entire movie. It's a movie will keep you on your toes.
