Agreed and double agreed. The Aragorn love story thing was overblown, and could have been ditched in favor of source material for example. And as you say, there are some changes that were made that did not make sense at all. Didn't seem to serve the story better, and ultimately changed the characters in ways that I thought were incorrect. I am blanking on a specific example I just read with my son, as I am reading them with my middle son now. Characterwise, Farimir, as you say, is a good example. But certain changes in flavor to the Frodo, Sam and Gollum trio in the last movie bothered me too.
I do NOT see how they can digest "Tower" into two books and do it any justice at all. If they do that, I might not even see them.
