People read fiction seeking clarity. One of the worst things a writer can do is to create confusion. People also read fiction looking for something better than reality, at least better than their own reality. So, keep it clear and concise and, most importantly, interesting… without getting too implausible.
It doesn’t have to be great, but it DOES have to be FINISHED. — William Arthur Holmes
UPDATE: …and then I saw where Lee Child had a similar but better quote: "Don't get it right, get it written!"
