"Is it art?" is a question that has vexed social critics for decades.  Here we face the question, "Is it porn?"  There are four sex scenes, and creative ones at that.  But the framing device is a guy jerking off in a video arcade booth, and from time to time the action stops as a woman faces the camera and tells him/you to put another quarter in the machine.  Full points for blurring the line between reality and fantasy, but in the end more thought provoking than arousing.  Definitely not for arcade viewing!
