I have a cheesy and cringe worthy idea for a BSG type show.
I suppose BSG1980 could be made into a more serious premise.
Its the near future in the long lost colony of Terra (Vaguely resembles our real Earth).
Its rife with it's own problems, but what it didn't count on was the Battlestar Galactica jumping into its orbit along with a Cylon Basestar.
With some Terran assistance it is destroyed, but that's only the start of the problems.
Far away the second colonial war is in full swing, and the colonials can't spare resources to deal with the lost colony given how backward it is, but the Cylons could easily send a few forces their way.
The Galactica is faced with a dilemma attempt to defend Terra despite being technologically behind or cut its losses and return to the colonies.
[Spoiler: Season 1 ends with Terra being glassed and the Galactica goes off after an alien signal.]
