Guy's comments make a lot of sense. I've always thought of the Borg as technology gone wrong. At the Collective's heart is a machine mentality, and the Queen is the mouth piece, the one who speaks. She translates for the machine, and what ever persona she projects is one deemed suitable by the machine. This machine has billions of memories, feelings, desires, and ambitions locked up in it's vinculums and yet neither the machine or its drones understand any of it. This is the great flaw in the Borg and it has been since the beginning when we were only aware of cubes and drones. The flaw was not as complex at first, but it was always there. Think of this, in TNG they didn't even understand that they needed to protect themselves from the simple command of sleep.
The episode that ruined the Borg in Voyager was Dark Frontier. Giving the Borg Queen that freaky dominatrix-mommy personality and making her willing to negotiate with people completely reversed everything established about the Borg.
I do understand the dominatrix persona and that some might not like it, but I find nothing wrong with that plot line. However I am somewhat insulted that you seem to think being a Mommy is a bad thing. Even in this day and time a sizeable majority of human females aspire to that designation, and a whole lot more have earned that designation and are very proud of it.
Hon, I really hate to break this to you but being a Mommy is mostly a very good thing.
I don't think any of this reversed a canon thing although it may have reversed some assumptions by part of the audience. The only reason the Queen agreed to work with Janeway on Janeway's terms is because just like Davy Jones in
The Pirates of the Caribbean, Janeway had two cannon pointed at the Borg's heart. That's really blackmail not negation.
What didn't really make sense about the Borg was the number of Borg cubes. If one was enough to almost destroy the Federation, the thousands they had should have conquered the entire quadrant. Either that or all the worlds around borg space should have been much stronger than the Federation.
Why would that be true, it may very well be (and there is some canon evidence to this fact) that the Delta Quadrant species had spent years studying and evading the Borg because they were a familiar enemy, in much the same way as the Federation became more adapt in defeating the Borg themselves.
Guy is right, they only send one cube because it never occurred to them that they might need more. That's a flaw, it shows the lack of creative thinking, and that is why all Borg roads lead to oblivion.
