It is by no means universally accepted that Atlas is poorly written. ("Universal" sounds like a collectivist standard in any case.) In fact we published a book on The Litrary Art of Ayn Rand." Here's the link:

And here's the description:
-----
"The Literary Art of Ayn Rand" focuses on Rand as a writer: the brilliantly distinctive stylist, the master of aphorism and symbol, the apostle of essentialistic characterization, the rigorous integrator who insisted that all elements in a work serve a single theme, and the igenious plotter who took pride in constructing her magnum opus as a "stunt" novel of mystery and misdirection.
Now in one volume, nine essays by six authors shed new light on the depth and complexity behind Rand's inspiring and entertaining writing. The contributors include:
Kirsti Minsaas: "Structural Integration in The Fountainhead and Atlas Shrugged"
"The Visual Power of Ayn Rand's Fiction"
"The Stylization of Mind in Ayn Rand's Fiction."
Susan McCloskey: "Odysseus, Jesus, and Dagny: Ayn Rand's Conception of the Hero"
"Work and Love in The Fountainhead"
Mimi Reisel Gladstein: "Breakthroughs in Ayn Rand Literary Criticism"
Nathaniel Branden: "The Literary Method of Ayn Rand"
David Kelley: "The Code of the Creator"
Stephen Cox: "The Literary Achievement of The Fountainhead"
