Masayuki Suo's I Just Didn't Do It is a courtroom procedural, yet one in which the central trial's outcome is of far less concern than the mechanisms of the Japanese legal system itself. With exacting precision, scant melodrama, and sparse musical accompaniment, Suo (whose previous film, 1996's Shall We Dance, couldn't be more tonally dissimilar) follows a young man named Teppei (Ryo Kase) as he's given a crash course in institutionalized injustice after being accused of publicly groping a teenage schoolgirl on a crowded train. Teppei immediately claims innocence to the charge, but given the offense's pervasiveness in Japan and the state's desire to stamp it out—resulting in 99.9% of all suspects being convicted—it's a decision with serious consequences, especially when he refuses to accept offers from cops, the prosecutor, and even his government-appointed public defender to plead guilty and pay the "parking ticket"-like fine.
