A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry. Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer. Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement. The origin of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, moving picture, photo-play and flick. A common name for film in the United States is movie, while in Europe the term film is preferred. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.

This movie was painful to watch. It started out with a solid premise (sort of) but then it lost clarity of the plot and muddled and morphed into pure atmospherics before a revelatory (sort of) twist at the end that did not really explain much at the time. The general feeling of suspense was quite effective, but the storyline poor and terribly inconsistent, and at some point the perception settled in that there is no rhyme or logic to this, and it's just inner workings of an insane mind that there is no reason that I should care about. In retrospect, when many incoherences have faded in my memory, the story makes more sense, yet the movie itself failed to effectively deliver its meaning during watching, and the only interest that kept me going was to see if this mess would have any kind of a logical conclusion. I think a mystery of this kind works well if viewers are periodically given cues that allow them to at least entertain some hypotheses in the expectation of the finale. On the contrary, Ne te retourne pas just kept piling incomprehensible visuals betting on the excitement of all puzzle pieces fitting together in the last 10 min. A lost bet with me indeed. What a waste of Monica Belucci and Sofie Marceau!

***LOTS OF SPOILERS***Okay, like a lot of the reviewers on here, this move left me very frustrated and confused by the end. Even if you were to believe the supposed explanation of the plot, there's still huge amounts of events that make absolutely no sense and are never explained. 1. when she sees her young self for the first time, why is her young self hit by a car? (not the near miss, but later in the background)2. What are the hand signals all about??? They never even attempt to try to explain this!3. Her sons mole, why in god's name would it move? Even if she was seeing him as her little brother, which I guess is what they were trying to convey? but still, why would the mole move from one place to another?4. What's with the table? They make this seem so relevant in the beginning and NEVER explain it. 5. Why would she imagine her brother as her husband?? The list goes on and on... This movie was basically a less interesting David Lynch plot line minus the intriguing camera work. It tries to explain itself too little to make it make sense and too much to make it truly weird and Lynch-ian.Other major flaws: In the beginning there's not nearly enough detail showed of the apartment to even pick up on what exactly is changing. The ending when the two women are writing together makes no sense at all. Is she the ghost of the blonde girl or her new self?? Seriously? No, no matter how you try to explain this movie, it doesn't make sense.

I must admit I envy the viewers that raved about this film in their reviews. My intelligence is not that vast. In reality, my intelligence is quite-quite limited, so I can only say that if during the first 15 minutes or so of watching this movie I was enthralled with it, little by little, because of its incredibly twisted story line, I was starting to have so many doubts and questions about the goings on on the screen, that eventually I lost interest in this very confusing dark movie.Many-many things don't make any sense, for example, Bellucci, all of a sudden develops a very noticeable limping --no explanation for it-- in order to lose it completely for the next scene and thereafter. What?What happened? Was she surgically intervened from an old crippling paralysis while the lights were set for the next scene or was just a shoe too small given to her by an unscrupulous wardrobe mistress? The change of actresses was done digitally in a very fascinating way, like in "The Legend of the Wolf", but much more subdued.The intervention of digital effects in straight movies will be, from now on, a fascinating tool to tell stories and also because unexpected in this kind of movies. Well, the whole thing attempted to be a superb movie, but it fell down on its face with a fatal crush.
