Not the best episode ever maybe, but it surely doesn't deserve all that scorn! "Shots of astronauts and the space shuttle used for time-filling"? Surely and episode about a space shuttle mission that didn't show astronauts and the shuttle would be a bit odd, and lets face it, on a TV show budget, they can hardly re-create shuttle launches and weightlessness half as realistically as the real thing! Speaking as a long-term science fiction fan, both written and TV/film, I thought it was a refreshing change to see a S-F/Fantasy about space exploration that featured the real space program instead of mile-long warcraft and laser battles.
