Although I loved Clint Eastwood very much as an actor, I have to admit that I appreciate him even more as a director because this man does not use the standard Hollywood tricks. He just knows to tell a good story, using only good a script and great acting. "Changeling" is the story woman's battle with the police and the system, and an indeed fascinating tribute to commitment of a person to break the corruption, cover-up and the excavation to find her child that she got taken from her. The film has few explicit scenes and an atmosphere that is really tough to follow. There is really a lot going on in this emotionally difficult and fantastically filmed movie, definitely worth your time and attention. A masterpiece.
