Now, I have to contest this. The movie Theoden was the most perfectly realized Tolkien character from the book, except perhaps for Galadriel and Gandalf. "We will not defeat them...but we will meet them in battle nonetheless." The Maybe you'd see this more in the extended versions. Theoden always overcomes his angst, and I thought PJ's Angst-ridden Aragorn was a little much. The book Ranger had no insecurities, just burdens and problems.
I'd not thought much about it, but I think you're right.
However, Galadriel loses because of the Halloween scene...
