We're not surprised that these gals sit around yakkin' it up about the wonders of Mr. Hydraulico almost as long as they get fucked by it; and we're certainly not surprised that they enjoy glorious multiple orgasms. More (DC) power to them, we say! However, it's still just scene after scene of, literally, the most mechanical humping on the planet.
Granted, the human element is not completely lost. Some scenes provide a second girl on the work site to offer words of encouragement and occasionally fondle the test subject, somewhat like the bedside manner of a second-year medical student. Solid white walls add to the clinical atmosphere.
Retailing: Terminators from the future will be back for more.
