While I'm all for rules in some things, the rules by Vance seem a bit egotistic. He reminds me of the mystery writer in SLEUTH who is always comparing the concept of mystery writing with some noble past time.

Perhaps, more similar to Disney's pirate's code (more a guideline than actual rules), these rules are of interest. But if you read the first 15 (all I could find), you will realize such authors as Doyle and Christie break them from time to time.

As for the movies, even in non-Chan films, the writers and directors are more interested in making something entertaining than "fair". To paraphrase David Bowie in LABRYNTH, "you keep talking about what's fair. I wonder what are you basing this 'fairness' on."
