Dystopian allegories
Nice article this week at Strange Horizons (note that I have nothing to do with the articles department, so this is praise rather than bragging): "The Failure of Fahrenheit 451," by Jeremy Smith. It has some nice insights about Fahrenheit, and it also serves as the first review of Oryx and Crake I've seen that takes the novel on its own terms, as a dystopian allegory and "if this goes on" Cassandraist (nice word) warning.
