The Reign in Spain: Three sisters in Madrid

I'll say this about Carlos Saura's Cria Cuervos (1976), Cry of the Crows? - I have no idea why it's called that: I fell asleep for about 15 minutes, woke up, hadn't missed a thing. It's a slow and careful, at times tedious movie, very much in the vein of "art cinema," and yet there are some rewards in watching it carefully and with patience. The story line is good: three young girls, sisters, in Madrid, lose both their parents and are being raised by a young aunt, along with a buxom, middle-aged household servant. The focus is almost entirely on the middle sister, the doe-eyed Ana, (spoiler, sorta) who has repeated visions/fantasies of talking with and inter-acting with her mother (I didn't figure out till quite a ways in that the "mother" is seen only through her imagination). In the first sequence, Ana hears noises from her father's bedroom and comes downstairs, sees a beautiful woman (a family friend, we learn later) rush out of the house in disarray, goes into the bedroom, sees father lying dead. She calmly takes a bedside glass, rinses it out, and goes back to bed. We gradually learn that she believes (wrongly) that some powder she's mixed into the milk has killed her father - a guilty she carries w/ her, but wears lightly. The father was a high-ranking member of Franco's Army, an old Nazi-lover and a truly nasty guy, as we see in various scenes (or at least 1 scene) from Ana's recollections. Over the course of the movie we see her coming to terms with her sisters, her aunt, and her new life, working through the guilty she'd felt at her imagined poisoning of her father (and later of her aunt), and in the final sequence the three sisters head off for the first day of school (the movie seems to span the course of one summer, though there are several scenes that Ana recalls from the past, in which she "appears" as a silent witness - to a fight between her parents, for ex.,and several scenes of a more mature Ana, maybe about 25 years old?, reflecting on the events of the summer). It's a movie with high ambitions that doesn't over-reach and accomplishes its goals, including a hint at the brutality of the Franco regime - although by today's standards at least the movie proceeds at a glacial pace that may put off some viewers or put them (me) to sleep.
(Note: Just looked up title, which is translated as Raising Ravens, which may make some sense as all three of the sisters have strikingly dark hair.)
