First of all, I'd like to apologize for the rather snarky tone of my previous post.

However, the author did continue to retrofit it into his evolving Middle-Earth through the Appendices and the Unfinished Tales, and they're just as relevant to his story as the other retrofits that made it into the book.
The Appendices to LOTR were part of LOTR from the very first publication of ROTK, and the
Unfinished Tales is a posthumously-published anthology of writings stretching across many decades. More importantly however, these writings about Middle-earth are mostly
not directly relevant to the story of
The Hobbit with the slight exception of a few small parts of the Appendices and
The Quest of Erebor. They are not, however, actually part of the story of
The Hobbit. Much of the legendarium is relevant to TH, but only TH itself tells the story of TH. (How's that for a tongue twister?)
However, it's a big deal adding a chapter here or there in later additions, as opposed to rewriting a chapter to fit better in with how an element is represented in the sequel.
I agree, but did Tolkien actually insert any chapters? I was under the impression that Riddles in the Dark was the biggest change he made, though I may be wrong. In any event, I think there is a difference between the original author making a later addition (or, to be fair, a scholar making slight revisions to give a more accurate version as Douglas A. Anderson did for TH and Hammond and Scull did for LOTR) and a filmmakers who is supposed to be making an adaptation adding significant elements to the story.
Tolkien said this with Lord of the Rings, and I assume he meant it for The Hobbit as well: the appendices should be treated as a part of the story that didn't quite squeeze into the breadth of the narrative. ... These are things that are a part of the story, but couldn't find an adequate way to ease into the story without feeling disjuntled.
If Tolkien couldn't fit it into the narrative, what makes you think the filmmakers could do better than the man who invented the story and world in the first place. Also, I think you missed an important point: the Appendices are appended to
LOTR, not
The Hobbit. TH and LOTR are, after all, separate stories.
the movies could accommodate for Arwen and still feel true to the original.
Without wanting to derail this discussion too much, I think it's highly debatable that the Arwen scenes were true to the original. At least they didn't put her in Helm's Deep though.
I'm certain that some details will be changed. This happens with movies.
I think everyone realizes that there will have to be changes to adapt the story from one medium to another, but I feel that changing the story itself defeats the purpose of adapting it.
