I don't think I'll ever get over how they massacred the concept of the borg in first contact.
The whole premise of TNG was that diplomacy, finding common ground, and respect are the path to lasting peace. The normalization of relations with the Klingons. Picard (and Spock) trying to somehow normalize relations with the Romulans. O'Brian stealth teleporting to talk down his old captain from stirring things up with the Cardassians.
This is why the borg were so compelling. There is nobody to negotiate with because there is no authority. There is nothing you can threaten them with, or anything you can offer because NONE of thier lives have value. They have no concept of a deal... an agreement of any kind. Why should they?
This is why they were scary. The federation playbook, the Picard playbook very specifically, was wildly ill suited for the threat.
The... suddenly it was like "oh, wait, actually there is a command structure. You can negotiate. You can cut a deal. Also assasinating the boss is a super viable route". They just abandoned everything that made them compelling.
Anyways, it's been like... decades... and I'm STILL pissed off about it.
So, whatever, it was already fucked before voyager fucked it.
