Defying Gravity Defying Gravity was more or less Grey's Anatomy in space. The story followed a group of astronauts on its way to Mars. Their exploits were constantly monitored for reconnaissance purposes and to see that these horny astronauts stayed out of trouble. Each one was fitted with libido-suppressing devices to make sure they kept their space suits on. Apparently, when you go to space all you want to do is roll around in the hay, or anti-gravitational chambers, and half of the show was about sex in space. Now that we think about it, what was so bad about this show again?
