Here's one thing I like about Soundwalkers by Raquel Castro: Much of it is in a foreign language, so as you are forced to read the subtitles, you can listen to the musicality of the language. Of course none of this tells you about the actual film, but that's not the point ;)
In the words of the author: "There are some fundamental principles regarding the construction of an acoustically healthy society, one where we can exist within the sounds of life. Respect towards voice and words, sonic awareness, the awakening of the sense of hearing. To preserve the sounds that tend to fade out, while remaining open to the sounds that spring out of each technological stride. To build an aural idiom that interprets its own symbolism. To accept the silence, enforcing it in the due moments. And, above all else, to listen."
