This film is easily the finest adult film of all time. Even forgetting about the somewhat controversial theme, the scenes are HOT. Kay Parker is so much more sexual than any of the modern porn "queens" it's a joke. Mike Ranger as her son actually appears to thoroughly enjoy himself (as you would, as it appears that he and KP carried on an affair after the filming ended...after listening to the DVD commentary on the re-issue). After listening to an online radio interview with Kay Parker from 1999, she mentioned that she was at first uneasy about taking the role due to the theme of incest, but decided that she wanted to be the one who brought a touch of "class" to the subject and decided to proceed. And thank goodness she did, because I doubt if anyone else could have done as good a job. Modern film makers of the adult genre should study this film and see what they should be producing, not the endlessly looped gonzo rubbish that passes for porn today. Even though Kirdy Stevens never recaptured the heat of the original, he should be thanked for this piece of porn's finest.
