Dana Ilie's Reviews > Flowers for Algernon

While this is clearly speculative fiction, the point of Flowers for Algernon isn't the technology that lets Charlie become more intelligent but rather how people react to him, both before and afterwards, as his perceptions of the world change. This is, in part, a sharp rebuke of the way that the mentally retarded are treated, but there are also interesting explorations of identity, friendship, and the results of revisiting one's past. There are several wonderfully memorable characters, particularly the free-living artist living next door.
The journal technique is quite effective in bringing the reader into the story and conveying Charlie's intelligence level, using spelling and grammar as superficial clues and the sophistication of Charlie's observations as a deeper clue to his current intelligence level. Over the course of the book, the writing slowly becomes more sophisticated, in tune with the underlying thoughts. I liked the balance between first-person immediacy and thoughtful retrospective that the format of a journal entry at the end of each day or two provides.
The reader's growing ability to understand Charlie and Charlie's attempts to understand himself touch on the exploration of alienness and human reactions to it that underpin so many great science fiction stories. Highly recommended.
