Among the many noteworthy reviews of Anne Frank by Francine Prose is this one by Janet Maslin in the New York Times.
"If there is a central point about Anne here, it is that she was a precociously self-aware writer rather than a spontaneous, ingenuous diarist. It takes a real writer, Ms. Prose points out, to hide the mechanics of her work and make it sound as if she is simply talking to her readers. Similarly, it takes a gifted explicator to make it sound as if she is presenting her arguments conversationally rather than creating elaborate, research-heavy diatribes to back them up."
