Why not try and read the book as it is and mentally separate it from the movies?
The book may feel a little bit anachronistic to today's audience.. hell, it opens up with a discussion about pipeweed and the merits of certain kinds (which ultimately does have some importance to the story
), not exactly how one would imagine a story to start about the ultimate battle between good and evil.
The book takes its strength from the imagination of the reader.. Tolkien goes to great length in describing Middle Earth and everything in it and it seems todays audience sometimes just don't have the patience or desire to lose themselves and create mental images themselves (something that could be said in general about general reading and stories).
So my advice would be to sit back, try to erase the movie pictures from your mind and enjoy the story.. let yourself be drawn into it and do not compare it to the movies. I guarantee you a wonderful experience if you're willing and capable to get lost in a story and enjoy it for what it is.
