I'm with you, Carlos.
Orson Scott Card (boo, hiss) wrote How to Write Science Fiction and Fantasy. In it, he opines that there are three types of SF/F fiction: Plot-driven, character-driven, and world-building. What I most enjoy are character-driven stories.
Examples of world-building are The Hobbit and The Lord of the Rings. They contain many side-stories (almost interludes) and characters that are memorable and endearing but irrelevant to the main story line. Those help to create such a magnificent universe.
You can find examples of plot-driven stories on best-seller lists -- and for sale in airports -- you can't put the book down once you start reading it, but the characters are all cardboard cutouts.
The stories Carlos writes are character-driven. the characters are so alive and fully drawn that they seem real.
BTW, Scott Card (boo, hiss) mentions that on a couple of occasions he'd written himself into an impossible and frustrating corner. As he wrote a novel, the story developed and grew in a way that there was only one inevitable outcome, the main character would do "X" and save the day; anything else would not be satisfying for readers. His problem was that the main character had taken on a life of its own, had developed and grown and made moral choices throughout the novel and become a person who would never, ever do "X," they just weren't that type of person and readers would not be satisfied.
