Of course it is simplistic. There are the goodies who are good and the baddies who are bad. The good ones are selfless, the bad ones are evil and want power. And Aragorn is amazing because he has king blood, he can even heal almost dead people because of it.
If LOTR was published today, it wouldn't have been considered a classic. Even WoT who is now largely criticised has far more complicated characters than LOTR. As I said, it is the fantasy Star Wars (or vice versa considering that it is older). It is epic and enjoyable but it is definitely shallow and simplistic compared to many of modern fantasy sagas.
Without wanting this to turn into an exchange of essays, I couldn’t disgree more. To read the LOTR and consider it to have binary morality between sides of good and evil is difficult for me to understand and it is this sort of critiscism I came to expect from the self styled guardians of literature whilst at University (most of whom had not read the book and most certainly not with the care they took when pouring over the language of Joyce). Clearly you are a fan of fantasy though, so this can’t be the case.
So, in terms of complexities of morality: the Numenoreans, Boromir, Denethor, the Elves entire history, the Dwarves entire history, the corrupting influence of power on any person (Frodo, Saruman,Galadriel, Sauron himself, Elrond, the afore mentioned steward and his son), the indolence of good men, the shifts in morality that occur in ordinary people, the perils of interpretation of events, the ring itself, the wildmen and pukel men’s subjugation, the layers of complex discussion on the nature of faith, the notion of how language defines a people, the corruption of Empire, etc, etc
I won’t even touch on the linguistic depth and the huge subtleties and beauty of Tolkien’s language, the former Don of English Language of Oxford, a man with a keen and idiosyncratic mind whose world building skills were unprecedented and, I would say, remain unmatched. As intellectual as Asimov, he did not lack complexity. He was however deeply conservative which I deem his major flaw.
You’re right it wouldn’t get published now. It is written in a style and with a narrative structure that no publisher would touch, it expects the reader to work to find meaning and a significant majority of genre fictions have ripped off the surface elements (including the trilogy format, even though that was a necessity of cost) to such an extent it would be considered derivative.
