I can answer this. because if you view the films in their released order, the machinations of the emperor can possibly just feel silly. I know upon first viewing the Phantom Menace, and lucas was like "Watch the movie, you'll see what the title means" I was like "Umm. yeah, Palpatine is working both angles and getting into power, so what? what is so pahntom about that. and why the hell don't the jedi see this, are they idiots? C'MON!!"
It wasn't until after a few viewing of TPM that I finally understood (and when george cleared it up for everyone in AOTC with the "dark side clouds everything speech"). when viewed in chronological order, plaptine's duality and evilness plays out MUCH better. IMHO
