Mature masterpiece
7 November 2002 | by shine-2See all my reviews

Another masterpiece from the portugese master. Very different from last years popular Je rentre a la maison. This work is more akin to films like Abraham valley and Francisca. An american audience would obviously not get anything from a film as refined as this one.

Camila (Leonor Baldaque) marries António but is the marriage based on love? What is the role of Vanessa? Camila is passive-aggressive and puzzles her environment and the audience.

The cinematography by Renato Berta is superb. There are no camera movements except when the camera is on a bus or a train.

It's hard to summarise a great work like this. Just another peculiar note. Camila is played by the writers granddaughter. The man who really loves her is played by the directors grandson. Both roles captures something of their makers, according to the director.

Anyone interested in serious cinema should see this. People who prefer braindead american cinema shoud stay away.
