"It's so bad." The line from The Wizard, the 1989 movie that was really a commercial for it, became the review. The Power Glove tracked your hand with ultrasonic sensors that needed three microphones taped to the TV, and it mostly didn't.
It sold about a million anyway, because it looked like the future on the box. It's the definitive toy of the "wanted it, never got it" pile, and the ones who got it wanted the money back.
