I recommend watching the movie without any detailed trailers. Your in for a treat! Lookout for screenings, VoD and Festivals to see this great work!
I have seen this movie by accident and was deeply impressed with the story, the visual storytelling and the continuous and never boring buildup (even though it had this mellow pace). The movie has an element of Memento to it through the use of repeating sequences. The intelligent and well guided evolution of the protagonist shifts the viewer from curiosity to dislike and finally resolves in empathy. A Masterpiece and a must watch for fans of good movie-plots and craftsmanship.
