On balance, I actually liked the movies. And I think they served the useful purpose of drawing a lot of new readers to Tolkien's books. But I couldn't help being disappointed by some aspects. I think Mortensen was miscaste as Aragorn; they could have done better with someone else.
Just out of curiosity, who do you think would have been a better choice? I heard they had someone else originally, but it didn't work out. I forget his name (he was in one of Anne Rice's movies)
