Excuse me for being somewhat new to /film/, I am by no means a film buff. I just watched through The Strange Color of Your Body's Tears. Here are some thoughts.
The movie has its own visual style, that is unmistakable. The overabundance of red light, mixed in with green or kaleidoscope of mixed coloration make it visually interesting for the most part. The scene where Dan is fighting with himself in his apartment, with the light continually changing from green to red on his eyes suggested to me "stop and go", as he is struggling with himself over the realization of his wifes death.
Early on when riding in the car and the car window is framed perfectly with the red light district window looked amazing as well. Red throughout the film associated with sex and blood. The blood looked surreal itself, not acting like blood, and the characters did not act towards blood as one would expect.
On the story, it is up to much interpretation so there is no one right answer. What I got out of it was that Laura was the key, either a woman with a split personality that was a murderer, or perhaps the first victim of a murderer. The 7 being an upside down L was something I did not get until they spoonfed me the three part screen where they were side by side. I do not think Dan murdered his wife, I think that most likely the murderer killed Laura first using the tunnels, and after the initial killing of what I would assume to be his love, he continues to kill in her name.
One of the major symbols in the film, especially in the second half was menstruation. Not just the ending, but the pads covered in blood symbolize periods, typically associated with a loss of innocence.
Thoughts? It was ok. Nothing I could recommend to anybody, but still more of an "experience". I will forget about this movie sooner than the creators hoped however.
