It seemed to me to be the antithesis of the Borg as originally conceived. I mean, yes, the Borg are indeed a single consciousness, but the way I see it, it's that very fact that makes it meaningless to speak of them (it?) occasionally
controlling a single body - it controls billions
of single bodies, all the time. On that account, no one body being more or less important than any other one body is pretty much the whole bit, isn't it?
I'm prepared to forgive First Contact as an individual piece for having it, because it's very, very tough to make a watchable action flick without an individual villain. But for me it marked the point where the Borg just weren't to be taken seriously anymore.
