Defying Gravity was set in the year 2052 and followed the lives of 8 astronauts on a six year mission through the solar system. Which is interesting enough as a premise until you find out the show was pitched to the networks as Grey's Anatomy in space and that their mission was being monitored from Earth via a real time communications. The later allowing the shows makers to give it a cheap to produce mockumentry feel as we follow the ongoing lives and relationships of the 4 men and 4 women crew. Sound dreadful doesn't it! Which is perhaps why it ran for just 13 episodes before being cancelled.
