now, now... lets stray from childish antics like name-calling...
I guess having TSOTS as a final climax would not work as well as we would all hope, at least not to those unfortunate souls who haven't read LotR.
It would be nice to see though. It kinda puts things into perspective. How the
War Of The Ring was a world changing event that effected all the
peoples of
middle-earth.
Sauron was mind was never bent on the destruction of
Arda like
Melkor was, Sauron was seeking total control of all of Middle-earth (see
Morgoth's Ring, Myths Transformed). The will of Sauron was a presence seeking to enslave the whole world. Even though
Saruman may not have known or intended it, and, I always thought that Saruman was still aiding Sauron even when he went to
the Shire, having his mind warped by Sauron through the
palantir.
So what it comes down to is that The War Of The Ring effected all of arda, nothing within arda was beyond Sauron's grasp in the long run and you can't really portray that and have the Shire remain untouched by everything.
But what works in a book doesn't always work with a movie i guess
