Another negative about the Queen concept is that, up until they showed her, the Borg were more alien. After showing a queen and drones and making them seem like a hive in that way, they no longer seemed as alien - they seemed like a rip-off of bees.
They took something original and "added" something to it that kinda took that away.
The presentation of the Queen and how bad guy is she detracts from the emotionless Borg the vast drone army, the Armada of cubes.
states the character should have been much more inpersonal, distant. Being sly, seductive doesn't match/tally with the reality of the remainder of the Borg.
Also why create the personage of Locustus if there is a representative already in the Queen to speak for the Borg. I know that's a matter of studio/writer decisions afterwards. But surely they could have gone down that line in FC - with another representative chosen - maybe an Admiral / Captain from Wolf, a one time friend of Picard now so alien/Borg in their manner, belief etc. That in my opinion would have been scary and much harder for Picard to contend with, especially considering the lengths gone to by his own crew to rescue him.
