Parodies and retellings

Retelling stories is a common way for critics to make a critical point about a work. The commentary might be humorous, as in a humorous parody; critical, as in a work that demonstrates the earlier work's failings of writing or perspective; or exploratory, as in a work that explores new dimensions and resonances of an early story.

Examples are particularly common within science fiction and fantasy, but have also been common outside of sf.

• The Wizard of Oz ... Gregory Maguire's Wicked and Geoff Ryman's Was
• The Hobbit ... Pat Murphy's There and Back Again
• numerous fairy tales & myths & folktales, including the King Arthur stories recycled by Marion Zimmer Bradley as The Mists of Avalon, which set off a veritable storm of retellings

Some non-SF examples:

• Gone With the Wind ... Alice Randall's The Wind Done Gone
• Lolita ... Lo's Diary
• Jane Eyre ... The Wide Sargasso Sea
