Aside from the human storyline, every other plot got much better
(Numenor did get a bit better, but still the weakest part of the show)
And where they left it , it seems like season 3 is going to be great
I'm assuming season 3 leads straight to (possibly ends with) the battle with Sauron described in the trilogy where he is defeated.
It's been an okay series. Not terrible overall, although there are some moments that are pretty badly written. It doesn't really have much to do with Tolkien other than it took some touch points from his novels and built a story around them.
The treatment of Gandalf as "the stranger" and especially the introduction of Saruman made little sense for the most of it. Saruman being presented as already seeking to rule middle earth in Sauron's place simply doesn't match the time line of his character, and certainly not Gandalf knowing that is his intent.
The Harfoots and Soori. Are they supposed to be precursors to the hobbits? These characters didn't make much sense and certainly didn't add anything to the story as far as I'm concerned.
The overthrow of the Queen and takeover of Numenor was too sparsely written, making most of the characters come across as cardboard cutouts, particularly the new king.
I'll watch a third season if it indeed leads to the great battle of all middle earth against Sauron, and I'll hope it's well done...
