I personally like this style. It juxtaposes the scientific nature of the "experiment" with the intense emotional elements that Charlie Gordon must contend with. The striking contrasts between the earlier and later entries, both in style and content, dramatize both the changes Charlie undergoes and the obstacles he must overcome. Even more dramatic is the contrast between the high-IQ entries and the final entries, when Charlie loses his intelligence and falls back into the semi-literacy of the earlier entries. Keyes's use of Charlie as the narrator makes the reader's experience of Charlie's inevitable fate more immediate and more moving, and shows that, as a reviewer in the Times Literary Supplement put it, Keyes "has the technical equipment to keep us from shrugging off the pain."
