I don't think I've ever seen Dark Frontier. Is it any good? I remember seeing bits of the first episode and not being very interested in it.
It really gives you some insight on how the Borg & the Queen function in unison & also explains about Seven's family and how and why they got assimilated.
I think once you see it, you may get a better understanding of how Voyager gets around the Borg due to the tons of information they aquire.
