Well, we could have a deep and thoughful philosophical discussion on the use of Christian symbolism in Lord of the Rings.
Or, we could have a somewhat lighter discussion about just whatever happened to the leaf clasp that Pippin left as a marker for Aragorn, Legolas, and Gimli to find, and whether it will be portrayed accurately in the movie.
Or, we could each make 50 posts of "Mine!"
But seriously, I love the dramatic interplay and symbolism in The Two Towers, particularly the use of Gollum's two natures (Slinker and Stinker, or Gollum/Smeagol) which can be compared to the two natures of man as described by.. um... someone... or what about the obvious meanings of the Elves leaving Middle Earth, or... er, Boromir was a jerk!
Oh, well, let's stick to what I'm good at. Mine!!
