A large part of the plot in this film is concerned with some sort of revenge, so the title is appropriate.  However, it's never really clear who is getting revenge or why.  Plot wouldn't be nearly as important, but in this case much of the film's precious 90 minutes is spent dealing with a nonexistent plot rather than the fucking, so you'd think there would be a little more clarity.

As for the sex, Jill Kelly, who only has one scene, and Erika Bella both give excellent performances.  All of the sex, bar none, is well-executed and entertaining.  Both Erika Bella and Antonelle Ballago have d.p. scenes which deserve special recognition.

The production quality is good, except that the entire film is dubbed (even Jill Kelly, who speaks perfect English, has ben voiced-over), which makes the film unintentionally comical at times.
