Premiered: September 17, 1978, on ABC
Premise: Big-budget sci-fi flop that was more than a bit reminiscent of `Star Wars' (with which it shared a special-effects creator). Set 4000 years in the future, `Galactica' follows the fragile fortunes of a caravan of spaceships fleeing to Earth from a galaxy dominated by mechanical beings bent on destroying the human race. The series launched on ABC and was canned the next year, only to resurface with just one original cast member in 1980 as `Galactica 1980.' The sequel died even quicker.
