A big part of using the Borg in Voyager, in my opinion, was probably so they could draw some parallels to TNG and introduce some established species and concepts from other Trek shows and try to draw Trek fans back in. I think it backfired and they just mucked up and species that had been really badass*
Voyager also sucked because the "trying to get home" concept didn't lend itself well for creating a consistent universe or strong narrative - It just can't work without some really strong writing. BSG did "trying to find Earth" pretty well.
Besides the fact that Voyager sucked anyway, I think it suffered a lot from Gilligan's Island syndrome where they would try some halfwit scheme to get them home and as a viewer you knew it wouldn't work. So it was like, what's the point in even watching this?
Voyager sucks.
*Badass until they were shit on in First Contact. LOL Borg Queen.
EDIT: We need a new Trek, set post-TNG that is serial in nature in its overall story. It can still be presented in an episodic fashion, but the that storyline still has to be there.
