The ending of the #Kdrama spin-off of the Japanese anime/manga/ #Jdrama, #Parasyte, was not surprising. They dropped all the hints in S01E01, so watch it carefully.
You see, in the strictest sense, a fanfiction is an unlicensed/unauthorised derivative of a Copyrighted work.
Since the Public Domain, and the Attribution and ShareAlike licenses (provided you follow the license terms), allow for anyone to create a derivative work, then any and all works based on it are not fan fiction.
Q: But how about continuity? And which one is “canon”?
A: Whichever the readers want it to be.
Most readers who are concerned about continuity and canonicity would automatically consider the work of the original author as the “Prime Reality”. Everything else are in “Other Realities”, or a branch of the timeline, or a parallel world.
The beauty of this is that, for literary works where canonicity and continuity is important, the original author can choose to declare this and that work are canon and/or part of the continuity. Those who did not read those works initially, will start to read them.
It creates an ecosystem where authors of a #SharedWorld can help each other.
In any case, an #author who dedicates their work in the Public Domain; or use an Attribution and/or ShareAlike license, more likely than not already understands how canonicity and continuity plays a role for their own work. These authors would have set their own guidelines already.
Example #1. Author A prefers to have complete control over the “Prime Reality”. That works fine.
Most readers prefer this, since this is what we're used to. At the same time, it doesn't invalidate derivative works; AND Author A can also reuse those derivative works.
(In fanfiction, most authors avoid reading them to avoid any possible issues; like fanfiction writers claiming the author stole their part of the story that was not part of the original source material.)
Example #2. Author B on the other hand declared that there is no “Prime Reality”. It is up to the readers to decide which particular path of the shared-world they prefer. It could be the primary author's (Author B), or it could be Author C, Author D, and so on.
Literally, there is no fan fiction in this setup. What would have been fanfiction are simply different realities (timeline/worlds/paths).
Watching Godzilla vs. Kong one last time before it leaves Netflix on December 31. Not that I don't have it in other formats 😂 but why not. I dig Godzilla stuff across the board. I guess some people hate on the USA ones, but Kong is always my main draw in these. And this one has some GREAT Kong stuff in it.
