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.
Adaptation Displacement: Let's face it, most of you have seen the movies, not the original stories. In a more direct example, in the first book, Zorro wore a sombrero and full-face mask. But McCulley liked the flat Andalusian hat and half-mask Douglas Fairbanks wore in the movie so much that he wrote that costume into all the later stories.
Newer Than They Think: Due to the iconic nature and well told storyline, Zorro is often thought to be an old folk tale from the settler days of California, and not a relatively new story made whole-cloth in 1919.
