I think you just have too much time on your hands. ;-)
But if you read much science fiction/fantasy you'll see that the patterns of setting up the good vs. evil are all very similar. It's the same story, it's a matter of how it's told. Kind of like John Grisham novels.
Still, I anxiously await the next installment of Star Wars and Harry Potter.
BTW - if you think Scabbers (Ron's rat) is like Chewbacca, you haven't read the fourth book...
I am asking my family to get a Babylon 5 paperback, Invoking Darkness: The Passing of The Techno-Mages. The 3rd in a trilogy. Lots of character development.
Right now, in my leisure reading, I'm finishing "Star Wars, Tales from the New Republic". After that I have "Star Wars, X-Wing #9-Starfighters of Adumar", "The Crystal Star", "The Black Fleet Crisis", "The New Rebellion", "The Corellian Trilogy" and the latest installments of the "New Jedi Order" to catch-up on.
I've been meaning to read the Harry Potter books, but I haven't been able to squeeze them in.
It would have been nice to re-read the "Lord of the Rings" trilogy before the release of the film, too. But hey, I have to make some time for Free Republic.
