I think I felt similarly about Tehanu at first, and it's still not my favourite but I've come round to it quite a lot. People change, their outlook changes and it recognises that. Perhaps she went a little too far in some respects but I can see what she wanted to do.
You might (or not...) want to read Tales from Earthsea and The Other Wind, which follow Tehanu. It didn't turn out to be the last book. To me, they sort of balanced out between the first trilogy and Tehanu. They reflect the views put forth in Tehanu but relate more to the earlier books, I think. Then again, if you're not into iconoclasm you might have a hard time with some of the stuff in those two books as well. I thought they were beautiful, although I still return with most pleasure to the first three books.
I'm generally not into rewriting of the worldview of my treasured childhood memories. But Le Guin does what she does so well that I at least have to pay attention.
Max Lucado's Facing Your Giants and Charles Dickens Oliver Twist. I'm kind of disappointed in Dickens' work. I really don't like his writing style. Lucado I enjoy his fun witty-ness on how he brings a Bible story to life in a kind of over-exaggerated way to where you can relate to a character.
Yes, I did hear relatively recently about the two books you mentioned. I look forward to reading them. Le Guin broke my heart with Tehanu (dramatic much?). Perhaps she could piece it back together. *spoilers ahead* It was heartbreaking seeing Ged reduced as he was, amongst other things. Not to mention the 'draco ex machina' at the end.
Now to look for Tales of Earthsea. I shall rave (or rant) on here soon.
