Good and underrated Argentine movie which is both an immersive psychological portrait of leading role character (María Teresa, a.k.a. Marita) and the depiction of narrow-minded stupid, sexist, repressive and morally cynical ethos of coward military dictatorship. Pace is slow, but works, for those who have nacessary patience, in order to developping Marita's confusions, anxieties, background and sexuality, in a very skilled performance by Julieta Zylberberg. School is a microcosm of neurotic search of "subversion" and self-affirmation punishment. All the oppressions must be overturned, at once if possible.
