I might be alone in this but it was not my favorite thriller. The way it was filmed, and the scenes took me out of the film, and I wasn't a fan of the acting in the film. However, I did love Margo Dunne played by Carrie Coon, Nick's sister in the movie. She was the comic relief in this twisted movie and she was really funny. They over did it with the blood/adult content, and I sadly was with my parents, yep, awkward. Plus I disliked the ending quite a bit, it left me wondering why I had wasted two hours to get no closure. I might still read the book but I'm not sure I will. 2/5 Stars.
