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: Most people think of The Secret as a self-help book, not realizing that it was based on a film that Byrne had released eight months earlier (she was, after all, a TV producer before she became a self-help guru). A fairly mild case, though, as the reason the book was released in the first place was because the film was such a runaway success.
