The borg were never especially intelligent, imo. But they didn't need to be, either. They had an overwhelming technological and numerical advantage over the federation, not to mention their utter disregard for individual safety. They were the perfect formula for a sci-fi boogeyman.-
The borg premise for VOY was really cool, a race that even the borg couldn't defeat, a new dimension the mighty borg had tried to expand to, and whose invasion was now backfiring. An awesome background for the story of a federation starship trying to get back gome. But for some reason however, they dealt with this crisis in two episodes, and proceeded to shiftr focus to neelix's emo tendencies. That's right, Neelix. The most annoying fiction character in a space opera ever, barring Jar Jar binks.
Suckage is the wor.d
