These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Badass Adorable: Inverted with Wile E. who is neither as threatening nor as cute as real-life coyotes.
Ugly Cute: Yet despite (or maybe because of) this, it's hard not to feel sympathy for the poor guy.
Death of the Author: While Chuck Jones "Rules" of how the series was written is somewhat well known, his contemporary Friz Freleng considered his account of the series rules apocryphal, saying he made up the rules long after the original shorts were finished. Considering how often some of the "rules" were broken in the original shorts, there may be some grain of truth in that.
Dude, Not Funny!: Wile E.'s suffering eventually reaches this. It comes to a particular head in "Zoom and Bored" to the point that the Roadrunner himself doesn't have the heart to scare him off.
Fanon Discontinuity: Rudy Larriva's eleven Road Runner shorts (and, arguably, Robert McKimson's two efforts along with the Sylvester/Speedy crossover directed by Friz Freleng) tend to be considered part of WB's Dork Age.
