Oh, man, is this pure goofy 70's; but fun. I like how the gaudy "transporter" effect takes so long to complete but she doesn't react to the psychedelic light show until it's over, then takes the appearance of an alien offering detergent advice in complete stride.
The dude looks more like a Romulan than Vulcan, but we won't quibble. And his parting line is creepy; "I'll be watching." But possibly she is a little turned on by the knowledge that her every private action is being observed by a tall, mysterious pointy-eared alien... whom she, and she alone, could get to open up and reveal the passionate but hidden feelings deep inside. All the while wearing the cleanest clothes in the galaxy.
