@Sci made it clear he thinks that the "Lost Ship" thing could last for 7 years, without anything bigger than that.
Well, no, I've said before that I think the "journey home" arc needed to receive some complications. I just don't think it needs to be
abandoned (just like I don't agree that the original premise of DS9 was abandoned).
Then we should be talking about alternative plotlines to replace the "Lost in Space" plot after 1 or 2 seasons.
I mean, no, we don't, the series ended twenty-two years and three presidents ago (almost four presidents, really, since only the second half of VOY's last season aired under Bush at the start of his term), and we're shooting the breeze on the Internet, not writing a series proposal for Paramount to remake the show.
But I think seeing
Voyager become a democracy and how different ship's parliamentary majorities come to power and cope with
Voyager's evolving political situation in the Delta Quadrant is one idea. Another would be,
Voyager getting suck in one region for a season or two and needing to build up a meaningful alliance of hostile cultures -- I think that was the premise behind "The Void," wasn't it? I'd also like to see something like "Year of Hell" but without the reset button at the end. Essentially a lot of the time, VOY would do a perfectly good arc but they'd artificially compress it into one episode when it ought to take up a season.
You mean like when DS9 had the Prophets destroy that huge Dominion Armada?
There are some fundamental differences here.
First off, the Dominion and the Borg are entirely different threats. The Borg, sans the Queen, are, from a literary trope POV,
monsters rather than
characters: they have no meaningful personality and do not act on motives other than the desire to consume the protagonists. The Dominion, by contrast, are
characters; they each have distinct personalities and act on distinct motives. The Founders, the Vorta, and the Jem'Hadar (and later the Cardassians) all constitute distinct sub-cultures within the Dominion, and those subcultures are in conflict with one-another to varying degrees.
The nature of the threat they pose is also different. The Borg are supposed to be overwhelmingly powerful -- a single cube is supposed to be capable of decimating over four dozen starships. It is, in other words, Godzilla vs. Bambi. They are supposed to be at a level of power where destroying a single starship should be easy, and their repeated failure to do so undermines verisimilitude.
The Dominion, by contrast, are powerful but they're not presented as inherently overwhelming the way the Borg are. DS9 S3 is all about the Federation building tactical parity with the Dominion after the destruction of the
Challenger. Individual Dominion ships can be somewhat tactically superior to individual Federation ships, but it's not presented as a Godzilla-vs-Bambi and adding more ships on one side or the other can even the odds.
Thirdly, even with the destruction of the Dominion fleet in "The Sacrifice of Angels," the Dominion
remained a credible threat. The war lasted another season and three-fourths, and multiple large-scale battles had to be fought. It wasn't a single ship just constantly facing down fleets of ships that were supposed to be overwhelmingly powerful and then winning all the time.
