Or, how about a Trek trapped in the future--the Federation has fallen, and the ship is weaker (to a significant, but not crippling, degree) than whatever race/federation/etc. is currently running things.
Sounds a shade like Andromeda
Ya know, I'm really, really warming up to the idea of an "Andromeda" themed Series. Federation in shambles and rebuilding itself throughout the Series. I even like in the actual Andromeda Series where Dylan had built up a 50 world strong Commonwealth and turned it over to the Politicians, and they got flushed back to square one because of their corruption (Though, of course, if they chose to crash it down again, I would want the show to last long enough to rebuild it back again to stay)
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
