I can understand where some people might think that LotR is actually TOO concretely right and wrong. (Especially with that line about having to fight a war, even though you don't feel like risking it? Peace activist Mortenson, grit your pearly whites!) The movie itself couldn't have been more clear about right and wrong. It's just a shame that the writers and staff don't like that idea quite so much.

I will not post it here because that is a side issue, off-track from fault-finding in the movies. Nevertheless, I found it to be an excellent article.
