Westworld is one of my favorite shows as well. (Have you seen Person of Interest? Same director, similar themes later on around S3-4)
I think you're right, that westworld doesn't have a lot of superfluous details - but the degree of plot complexity required to make use of all the details it contains has led some critics to call it convoluted.
On the other hand, the Lord of the Rings trilogy - the movies are full to bursting with strange details that never make any difference to the story. Bilbo's birthday party is one immediate example - there's a bare minimum needed to establish some characters, and then on top of that are details just there for the sake of themselves.
