Do you think Tolkien would be insulted by the LOTR movies?

[Beleg]

Though I enjoyed the Return of the King, The Two Tours is for me the worst film in the trilogy.
I agree that PJ could not adapt the whole story. But why did he include scenes that didn't even exist in the book, instead of real events related in it? If he didn't have the possibility to do so because the books were too massive, he shouldn't have added others imaginary scenes (death of Aragorn, Elves in Helm's deep...).

About this last point: for me, the coming of Haldir was a mistake. The end of the 3rd Age shows the end of the Elves. They are all leaving Middle-Earth. And it's something that I really notice each time I read the books: it's the time of Men, with the 4th Age coming.
So, why should the Elves get involved in the war and help the humans in Helm's Deep battle?

Anyway, I enjoyed the two others, with just one great disadvantage: each time I'm reading the books, I have the faces of the actors instead of the ones I've imaginated until now. And for Eowyn, it's very annoying as I find Miranda Otto very far from what I was thinking. Fortunately, I'm quite happy with Boromir and Faramir.

EDIT: I lost the thread of the conversation. I meant by this answer that Tolkien, if he would not be insulted, would be (maybe) irritated by some aspects of PJ's adaptation.
