[Balin999]

With your leave, I will try to give a definition why I like/love/admire Tolkien.

First of all, Tolkien's style of writing is just uncomparable.
He can describe things in such a way that you can actually see them in your mind.
For example: Rohan, you can actually smell the gras by reading the description!
Or Fangorn, the old forest, or Gimlis explanation of the caves of Helm's Deep! I think I read it 5 times before I could go on (but then, I really like everything that has to do with caves).

Second, the LotR is a story that is uncomparable, too. (IMO) There are so many themes in it, of love, of friendship, war, death, tragedy, joy, treason, ....
and the whole story just grips you page by page, you can't let go of it. You always want to read on, you live and die with your favourite characters, some of them almost becoming your friends as you travel with them down south to find their destiny. You can actually lose yourself in the story, for example on a day where you have nothing else to do but reading the books.

Third, you can read it 300 times, and it won't get boring. You discover something new everytime you re-read it. Some parts you can't remember, some parts you can never forget.
And I think that there is a lot of wisdom in the story, such kind of wisdom your grandfather tells you while you're still a small kid, Gandalf talking to Frodo in "the shadow of the past", for example. And his famous "do not deal out death in judgement" sentence, one of the wisest things I ever heard in my life.
And Tolkien tells us that nothing is that bad, when you got a good friend at your side. (frodo and Sam, the Fellowship).
Well that's all for now, I'm sure I will find more later on.
Yours, Balin.
