The original Borg were a collective of many equal minds and voices, assimilating other cultures in order to move all towards perfection. There was no malice in their claim that 'resistance is futile'; to them it was just a statement of fact. Locutus was an emissary, a face for the Federation to react to and a mind that knew how they thought to allow the collective to plan its approach.

(quotes)
Oi! The Borg were good in First Contact! Leave the Borg alone!
Then suddenly, up pops the Borg Queen, a devious, sinister tramp who just wants to make everything like her. Suddenly the Borg are another tedious hive race, and their 'adaptation' is reduced to a limited invulnerability to phaser fire.
In Voyager it gets worse. Species whichever show up and the Borg can't beat them, however many times they try exactly the same thing. They have to get a Starfleet surgeon to help them adapt their own nanoprobes, when adaptation used to be their schtick. The second time they tried to fry a cube with the big energy pulse doodad, it should have bounced off; likewise the transphasic torpedoes only should have worked once before the Borg got the idea.
Six million minds hooked into a massive parallel processing array; analysing threats, running simulations, designing solutions. They didn't get where they were today without knowing how to deal with new stuff, yet suddenly 'new' seems weird and scary to them, because they've become brainless drones to the silly baggage in green rubber, and she's all distracted trying to, hem, interface with Data.
I liked First Contact, as a film in its own right; I just thought it served the Borg badly.
And if all Borg are controlled by the Queen (or possibly Queens), why didn't she have words to say when Hugh and his mates all ran off to be individuals.
And how come the Borg can assimilate a society full of individuals without all wanting to climb every mountain, but one Borg gets ideas and suddenly the cube is very much alive with the sound of music?
