Gone Girl
This film is a hidden gem by David Fincher, I had heard about it but I had never dared to watch it because it is more modern. With zero expectations, I suddenly find myself immersed in the story, with moments where I was actually worried about the protagonist. The film also shows, in a rather ingenious way, a biased story so that your opinion about what happens changes as the truth is discovered, something that I appreciate a lot in a film. Without expecting anything, it blew my mind and even made me nervous about what was going to happen. Highly recommended movie.
