Sci-fi books/films/tv shows with a utopian civilization are a dream to live in (as the definition of utopian would suggest). There might be large and small problems & issues along the way, but overall the same humanity that causes these problems also solves them. All in all a nice society based on humanistic principles.
Most of these civilizations came about after great devastations, usually from all-out world/planetary wars. And while these stories are entertaining and wonderfully enchanting, I always feel some dread.
We are on the wrong side of the timeline.
Uh oh, we’re doomed!
