It's actually a pity, the initial idea is quite appealing and the title and the advertising strategy have aroused great expectations. However, the film gets lost in a long series of quotes, stylistic devices and plot patterns, which were borrowed or copied from the works of famous directors. Thus, despite many mysteries and twists, the story becomes more and more predictable, and thus more disappointing. Unfortunately, the film completely lacks its own cinematic language, which would be necessary to remember the film as an independent work. As it is, however, it remains only as a thoroughly successful homage to Aldrich, Polanski, Lynch, Hitchcock, Truffaut, and, and, ... in memory.
The film is most convincing in its image composition, the black and white photography is beautiful, followed by the excellent actors. What the film would certainly have scored with is almost not used at all: quantum mechanics is only briefly mentioned, and the main character's groundbreaking theory is never explained, although it seems to be the key to the story. Instead, the emphasis is entirely on confusing the emotions, leaving many interesting possibilities for interpretation. The story never builds up to the great mystery that the title implies and becomes more and more annoying and shallow towards the end. What remains is a visually splendidly made film that is strangely conservative in the end.
