One of the weaknesses of the two 'Blind Owl' movies is that they presuppose a familiarity with the text. A truly great movie about this book would give you more insight to it. Ruiz layers the movie with metaphors, and movies within movies. Ideally they should make you want to read the book. The book is considered a masterpiece, but there's a caveat in that it caused people to commit suicide. Another 'Gloomy Sunday'.
Bewitchingly organized and stylized-- would require more viewing for me to decide if it's good or not. But then again, Luc Moullet wrote this in a highly favorable review: "I've now seen 'The Blind Owl' seven times, and I know a little less about it with each viewing."
