Better than expected considering they cant use the silmarillion. They DO NOT have rights to the Silmarillion, so what story exists they cant use. They only have rights to LOTR and associated texts.
Those expecting an exact reproduction are therefore going to be out of luck, things will be different.
As detailed as Tolkiens work is the second age is patchy, with very little dialogue so everything you see on screen is original. The history we have is full of gaps, hundreds of years of nothing, if you were to represent that on screen it would be patchy and messy. I have no issue with compressing the timeline or changing character.
In terms of what we got I seemed well realised. The pace is slow, but thats better than 90210 in middle earth, as many feared it would be.
Lots of criticism of Galadriel online, but this is how she was! She was more aggressive, ambitious and prideful , even right into the third age. Remember she only finally matured when she passed the test in LOTR.
Its not perfect, but its much better than I could have been, its solid and ill watch it all.
