[Eomer of the Rohirrim]

I wonder how they would have pulled off an Aragorn v Sauron fight as well as showing the Eye during the destruction of the Ring.

Newbies would be all - "So there's TWO Sauron's! One of them's an eye and one's a monster!"

I wonder. Maybe that's why they left it out, rather than because of the uproar on fan websites that has been suggested as an explanation for leaving out the fight.
