Hi Paul, and I am just seconding
Galadriel55 here in welcoming you. I'd say she is being unnecessarily humble and I think pretty much everyone here is a loremaster of sorts. So I very much invite you to take a look around, dig for questions and answers, ask those of your own and share your own discoveries and insights. You will surely found many local Barrow-Wights interested in discussing nearly any aspects of the vast lore of Arda.
And as for the films - I daresay we are a mixed bunch here, but even those who are rather on the critical side (I would count myself among them) aren't opposed to discussing them, and perceive and appreciate many of the films' positive elements.
So welcome to the 'Downs, and enjoy your stay!
P. S. As for revealing something you did not know yet, just taking a shot here - do you know what Amon Lanc is?
