With the way you're arguing this topic, pretty much everything that has ever been made from a source has not been a faithful adaptation.
Not even remotely accurate. I've said multiple times that I consider Jackson's LoTR reasonably faithful to the source material, despite a multitude of changes.
It really seems like most of you have never actually read The Silmarillion, Unfinished Tales, etc. That's all well and good, but if you haven't, you really don't know what you're talking about.
This is all tiresome as shit now and none of us have actually even watched this stupid thing yet, but one final attempt...
Imagine you are a skilled wood worker and you've been tasked with building a writing desk that's accurate to the Tudor period. You're provided with all of the wood, fasteners, adhesive, tools, etc, that are necessary to get going on the job. Because you are skilled and experienced, you can be expected to turn out a respectable product. Sure, it's not going to be 100% identical to an authentic writing desk from the period, as you'll be forced to take some liberties and are limited to modern materials, but it'll get reasonably close. This is akin to handing the LoTR books to a skilled filmmaker and tasking him to adapt them into movies.
Now imagine that you're that same skilled wood worker and you've been tasked with the same job, except this time, instead of wood and proper tools, you're provided with cotton balls, Elmer's glue, and brown spray paint. This is akin to handing The Silmarillion to a skilled filmmaker and tasking him to make a long-form TV show out of it. It's simply not suitable for the medium, unless you are okay with COLOSSAL liberties being taken that would reach well beyond whatever stupid diversity casting or other modern political motivations might be in play.
