it is the most comfortable definition. and, maybe, the most precise. because, except the trip of an ornithologist across a forest, strange meetings and fantastic adventures, nothing could be known. but, it is not exactly an enigma. and not a cryptic improvisation. it has a lot of cultural references and this does it, in same measure, a religious film, an art film, a form of fairy tale - the rules are the same - or an experiment remembering Bunuel. but significant is not what the director says . the key remains the final feeling. without a reasonable name but who could be defined as fascination. and this is the basic virtue of this challenge/provocative film. to recognize pieces from Romano Catholic hagiography, to see fragments of expressionism, to admire an eulogy of psychoanalysis or the deep solitude like a source of escape from yourself.
