20 episodes out of 168 might not seem like a lot on the surface, but it surpasses the number of episodes from both TNG and DS9 combined that dealt either directly or indirectly with the same subject.
What about the Dominion War? Heck, the six-part occupation story from season six and the nine-part final chapter from season seven give you 15 episodes alone.
What does the Dominion War have to do with the Maquis? That's the subject I was talking about.
TNG did 9 episodes that dealt, either directly or indirectly, with the concept of the Maquis, and DS9 did 10, for a total of 19 Maquis-related episodes total spread across two different series, as compared to the 20 episodes from Voyager that dealt either directly or indirectly with the concept.
Anyway, the point I was trying to make is that, contrary to perception, Voyager didn't actually veer away from the Maquis angle; it just utilized things differently than was originally intended.
