The paper lacks individuality. The writer may not have understood the assignment or may simply have felt indifferent toward the topic. No voice emerges. The result is flat, lifeless, very mechanical, and stilted. Imagery is strong.
Expression is fresh and appealing, fun to read.
The writer often settles for the first word or phrase that comes to mind. The result is a sort of generic paper that sounds familiar, routine, or common place. The writer is struggling with a limited vocabulary. The words tend to be dull, colorless, and trite. Word choice may seem careless, imprecise, or just plain wrong.
