The Eye of Sauron is a very heavy motif used throughout the book, Jackson taking such an impactful literary device and turning it into the iconic cinematic visual it is today was very well done.
To be fair, the eye looks cool and gives the BBEG some much needed character, instead of being the nebulous master of evil he is.
I don’t think the eye is bad but I prefer how it is in the books, the mystery makes him more intimidating to me
A half ethereal necromancer with boundless sight who can possess an entire tower wasn’t intimidating enough for you?
My head canon was always that the eye was just a spell or a possession ability he had while he was working to come back (which required the ring).
I can’t remember how it was in the books
Frodo sees an eye, that looks out through a window in a room at the top of the tower. Some speculate, that it’s the Palantir in Barad Dur.
Damn, being spied on by an evil overlord via palantir. Such fantasy. Such whimsy.
