Some people like that kind of story.
A friend of mine loves the movie Dune, citing its world building in particular, while I was bored by it being more of a character guy.
Ideally a story should have a balance of good world building, plot and characters,
but I find that I can forgive a dull plot or shallow world if the characters are engaging.
So I think there's an audience for a world building focused story, even if it's not you or me.
