I've tried for three days now to get my thoughts coherent on this one, and I think I've finally pinned it down to two Principles of Fanfic:
- You can make anything work, but
- you have to be clear what you're changing - and know the rest well enough to know what you're not.
Fanfic is about change. At its most gentle, it just backfills a scene that Tolkien never recorded: Bilbo choosing the gifts to leave after his departure, for example. Sometimes the change is to add a character, either away from the plot or in it. Sometimes it's to change the style, perhaps to give an irreverant retelling (see
the Leithian Script)
). And sometimes it's full AU - Sauron gets the Ring, Elrond goes to Numenor, Ulmo turns evil instead of Melkor.
And all of those can work! I strongly believe that any story concept can be well-written, however outlandish it seems. But to do it properly, you have to know the canon well enough to see exactly what changes you need to make - and to make
only those changes, and know what the consequences of them will be.
Coming back to
Rings of Power: from their legal position, their One Change is the compressed timeline. Being unable to even admit the Silmarillion exists, they can't treat (say) the absence of Celeborn as a change: they are legally required to consider it gap-filling. But
we can still think about them as changes, and judge them that way.
You asked "Is there a formula by which fan fiction is to be judged?" I think there is, at least from a changes perspective:
- Do the changes affect the plot as they should?
- Do they contribute to the story being told, or improve the viewer/reader's experience?
