I am a big fan of the movies and rewatch them almost yearly, so I felt it was time to finally read the books. Obviously, I already knew I like the stories and characters, but it was really interesting to now meet the full story.
And it really is beautifully written prose, too, and way funnier than I expected.  Also the themes of not losing hope and friendship stand out even much clearer.
I was disappointed to realise, that Arwen being a badass good girl and saving Frodo from the ringwraiths is a movie only thing, though..
