every so often i'll come across a post in one thread or another where people will mention how the borg appeared too many times or how they were 'watered down' or even, 'castrated'. i know, the last one sounds unbelievable, but i've seen it used 10+ times in reference to the show.
the borg were the recurring villain VOY needed as an overarching villain. they worked the same way the dominion did on DS9. in the beginning they were displayed to be unstoppable. the obliteration of a fully fledged galaxy class ship, the flagship of the federation. over time, more weaknesses were discovered: jem'hadar reliance on white, the founder disease, the vorta selfishness, i could go on and on. these weaknesses are necessary for the show's good guys to be able to fight and eventually, win. it happens on every season length show with an overarching 'big bad'.
the borg were what kept me viewing the show each and every week. they're half of what made VOY such a great show. the same goes for DS9. to be honest, without the dominion, i don't think i would have stuck with DS9. the scenes on cardassia prime are just so much more enjoyable than anything we see from the federation, bar section 31.
