The Good: "Star Trek" and "Star Trek: The Next Generation." The Bad: "Battlestar Galactica" -- That space station was really not the best place to shelter the surviving remnants of the human race. The Ugly: "Firefly" -- The Serenity may be a beloved home and a representation of freedom, but it's also used to transport cows. Also, the engines sometimes break. That causes big complications in space.
