... I like my fantasy and sci-fi dark: Lord of the Rings rather than Narnia, Mass Effect rather than Star Wars or Star Trek (though I do also like Narnia, Star Wars, and Star Trek, incidentally).
Technically, of what you mentioned, only StarTrek is utopian scifi. It’s been so long since I’ve read any that I’m not even remembering any other utopian authors off the top. Star-Trek, even with it’s battles and conflicts is a version of Utopian since the trials of everyday life such as earning a salary, getting medical help, paying for education, are all things of the past. Since there are still social classes in movies like StarWars where people fall prey to the vagaries of life, it fails the basic test of utopian.
