Krypto-Revisionism is a concept created and named by writers Steven Grant and Mark Evanier, and refers to any storyline, concept, plot, or idea that an audience chooses to reject.
- "I was over at Mark's for lunch one day during my Los Angeles years, and we were discussing the then-rampant trend for writers to come onto a book and in some story twist suddenly declare part or all of the previous continuity invalidated. (The 'everything you know about _____________ is wrong' syndrome.) Specifically we were discussing the John Byrne reboot of Superman. He referred to it as 'revisionism,' as in historical revisionism, the reinterpretation of past invents from other than canonical points of view, and I named it 'Krypto-revisionism,' as a pun on the concept 'crypto-revisionism.'"
This concept is especially crucial in order to enjoy a fictitious universe with numerous authors. For example fans of the Star Trek shared universe may choose to reject any episode that does not fit in with their view of said universe. This is not to say that the viewer denies the episode's existence, but rather mentally sets aside any facts stated in the episode. A prime example is the Star Trek animated series, which many viewers chose to ignore.
Another example of this would be the Highlander movie franchise. Many people chose to ignore the second movie because it turned everything laid out in the first movie on its ear, more or less just to make a quick buck. The makers of the third Highlander movie practiced their own form of Krypto-Revisionism and continued the franchise in the vein of the first movie, choosing to disregard the whole plot of Highlander 2.
