Attacked!!

Attacked , Os? aka Attack is a 1978 Japanese film in the Violent Pink style of Nikkatsus Roman porno series, directed by Yasuharu Hasebe and starring Asami Ogawa and Yko Azusa.

The films ending, in which the attackers identity remains a mystery, has generated the most polarizing comment from critics. Some consider this a suspenseful, unusual plot strategy, while others dismiss it as teasing the audience. In their Japanese Cinema Encyclopedia The Sex Films, the Weissers write, the unsettling nature of this denouement generates considerably more tension than the standard thriller, as the viewer cant shake the feeling that the story hasnt ended at all. The fear continues long after the credits insist its The End.The Weissers judge Attacked to be a step back in the brutality Hasebe portrayed in his offensively appalling Rape 13th Hour 1977, writing, The film is still deplorable, but not nearly as repulsive as the former notorious entry. Allmovie also notes that this film is less extreme than Rape 13th Hour, but that Hasebe nevertheless creates tension through the suspenseful plot. Of the attacker never being revealed, Allmovie comments, The ending feels a bit like a cheat to those viewers attempting to guess the rapists identity, but the film holds together as a solid thriller nonetheless. ........
