The criteria here are somewhat subjective - I will make the final determination so I will not bet. Some important considerations will be:
Does the movie/series have the same title as the book or the series of books to which the book belongs?
Are most of the major characters named the same?
Is the plot roughly the same?
Sometimes plots are changed / characters are combined in the adaptation process, but that alone isn't enough to make something "not an adaption"
Feel free to add multiple books from a series, but note that if a TV or movie series is covering a book series one book at a time, I will only resolve YES if I think the series can be said to have adapted the particular book.
FAQ:
I will resolve adaptations YES, even if they were adapted before this market was released.
It doesn't matter if it's animated or if the animation or writing is partly or completely AI-generated, but it does have to be on the level of quality so that I feel like I am watching a Hollywood movie or major-streaming-platform show, rather than a piece of experimental cinema.
The adaptation also has to be legally licensed by the copyright holder and available to the public for consumption.
