Wolfgang Mozart's older sister was exceptionally talented. And, as she grew, her family discouraged her and put all their energy into her brother and pushed her to marry and have a family. All this is shown in the film and cannot really be refuted. However, the filmmaker's have decided to take some liberties--to ASSUME certain things about Maria Mozart that we simply do not know to be true today. In that sense, it's quite a bit like "Amadeus"--fictionalizing history a bit here and there. The story has a strong feminist bent--and even goes so far as to attribute much of Wolfgang's talent to her! This is rather dubious, as Wolfgang clearly was insanely gifted. It's an intriguing idea--but there really isn't any basis for this assertion. Now this complete fiction COULD have worked--but the rest of the story is incredibly dull--very, very mannered, slow and lacking anything to hook the viewer. 'What if' just isn't enough to carry the rest of the film and I felt EXTREMELY restless as the film progresses. My butt also fell asleep--and it's a great judge of whether or not a film is too tedious!
