Boy, what an idea! Take a bevy of buxom beauties, rent a boat, stock it with horny young studs and a good supply of non-oxynol 9 (anti-AIDS spermacide), and film the results. Should make a terrific movie, right? Wrong! And what's most surprising is that Grafenberg Girls Go Fishing comes from people with so much experience in the business and so many good films, they'd know if they had a clunker on their hands.
Oh, the women are beautiful, willing and experienced in XXX films, as are some of the men. But they've been put in situations that are only rarely erotic, and even those scant minutes are sometimes ruined in post-production. For instance, the sound, including dialogue, seems to have been added after the fact. This destroys the realism of the scene. And yet, every once in a while the man and the woman actually appear to be having a good time. Too bad such moments are fleeting. To prolong the mood, one would do better to turn off the sound and watch the fireworks show at the end.
In the meantime, you might want to take another look at The Grafenberg Spot, a Mitchell Brothers classic from last year.
