Sure there's some ship or phaser action in there but there's no Good vs Evil driving it.

"Resistance is futile."
Out of all 178 episodes of TNG, only about 6 of them physically featured the Borg. In the episode "I, Borg", we are introduced to the concept that the Borg are not Evil and can be sympathetic. So we could say only 5 episodes featured the Borg as antagonists. If we take this a step further, the two parter Decent features two factions of Borg, thanks to Picard's decisions in "I, Borg." The opposing faction is being manipulated by Lore. The rebel group is lead by Hugh.
While the Borg are introduced as antagonists, much like the Klingons, Romulans, or Cardassians, they are not labeled as evil but as a race that holds aggressive ideals that can be reasoned with.
Which is my point entirely.
Star Trek is not about battles of good versus evil, unlike Star Wars. The Borg are a race, or collective hive, of species that adapt and try to improve themselves for the benefit of the whole instead of the one. They are just another civilization that runs by a unique logic.
In Star Wars, you have the Empire. They are evil. They want to control the universe and they will blow up planets just because. You can try to argue the Empire's motives and that the people who comprise the Empire aren't evil, just their Emperor. But the movies do not make this argument. If they did, they'd have some explaining to do when presumably thousands of innocent workmen die in the great Death Star tragedy (and again when construction on the second Death Star is bombed.)
There is no negotiation with the Empire, there's no middle ground for understanding. It's light sabers out, choir-chaotic music on. It's feeling over thought and that resonates more with action figures.
Case and point: In TNG's "Silicon Avatar" the Crystalline Entity returns, feeding off planets and colonists. Naturally, some want this alien destroyed because it's devouring humans and destroying colonies. But Captain Picard hunts the being to find a peaceful resolution... to understand it - not to destroy it. Picard makes the argument that the Crystalline Entity has as much right to live as a human and they may be able to find another way for it to feed or live.
Star Trek had an opportunity to go a "good versus evil" route by saying "Crystal monster BAD! Federation GOOD!" But it didn't. It went with
negotiation.
Check.
