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 Decay: Meg Cabot's 1-800-WHERE-R-U books are about a teenage girl who acquires psychic powers and tries to find missing children without attracting the attention of the FBI while also navigating a teenage romance. 1-800-Missing is about a woman in her twenties who almost immediately goes to work for the FBI as a special consultant. The TV show exists in the book universe, where the characters complain about the changes.
