what you're criticizing is what a lot of people love about faulkner. he had beef with hemingway because of how simple his sentences were, and hemingway made the same critiques about faulkner as you have. an argument could be made that faulkner's prose was the antithesis of hemingway. or hemingway was the antithesis of faulkner. either way, they're both poets in a sense, and your preference is up to your own subjective taste.

you get a glimpse of it in this speech: "It is easy enough to say that man is immortal simply because he will endure: that when the last dingdong of doom has clanged and faded from the last worthless rock hanging tideless in the last red and dying evening, that even then there will still be one more sound: that of his puny inexhaustible voice, still talking."

so beautiful! especially, "the last dingdong of doom has clanged and faded from the last worthless rock hanging tideless in the last red and dying evening" -- to me, that's very lyrical. only a poet can do that. and in that paragraph, he repeats "last" three times, which adds a nice cadence and rhythm.

i personally like faulkner's prose. it's especially refreshing to read in 2021 when everything is written in plain, simple english. not everything is some code or a README.
