Read any one of Jack Williamson's stories and you will say "No wonder he was relegated to cheap pulp magazines! This stuff is about as sappy and 'atomic' as it comes." And you'd be right, sort of.
The typical Williamson story breaks down like this: A man is going about his business in the regular world. Something happens (something extraordinary) and he is transported to another world. The female who will become his love interest is present at the extraordinary happening, or appears soon afterward. A conflict is introduced via a bad guy who threatens them directly or simply prevents their return to the normal world. Action ensues and the protagonist wins out in the end, usually through the MacGuyveresque application of some scientific principle. All ends well, with the hero and his girl destined to live happily ever etc.

"The Green Star", for example, reads like a cross between Star Trek and a game of Candyland. Our hero arrives in a future world where all human needs are taken care of yada yada yada. The description that Williamson gives of the world of the future is the kind one usually gets from 50s science fiction. Things are "atomic" and all the problems of society are solved with "science".
There environment is a bucolic wonderland of perfectly manicured lawns and shrubs separating futuristic houses shaped like white towers. There are levitating rocket cars that shuttle men and women to home, work, or play. Cut gemstones play a very large role in the world of the future. They provide light, roofing, and a form of currency. They also provide Williamson with an endless supply of metaphor for the new inventions he witnesses.
The landscape of the future prompts him to write, "Here and there were low, forested hill, meandering silver brooks bordered with emerald verdure." When he meets the obligatory monster, our hero remarks that, "The red eyes were hard and cold and malignant as frozen rubies." The effect of all this comparison to jewels does give the future a gloss of the shiny and perfect, but it is so out of line with reality that it comes across as more of a hallucination than a vision of the future.

Make no mistake, Williamson is not deep reading. I fall back on WIlliamson when I am looking for literary popcorn. I read it with the same smile that I read Howard's stories of Conan the Barbarian or watch an episode of Mystery Science Theater. They are fun and illuminate the spirit of their time even where they fail at things like character development and believable plots.
To be fair, Williamson's work might suffer from that affliction that strikes artists and writers who started something that went on to be imitated extensively. Their work seems cliched now, but it was groundbreaking at the time. Nah...
