Cool which one? Episode 3?
Actually, I've been watching them all in order, from "Phantom Menace" to "Return of the Jedi", as a celebration.
I'd already watched ep. III, but I made the mistake of watching it alone, and my Dad said he wanted to watch it. So I had to watch it a second time, along with watching ep. VI. They go good together.
I'm kind of "Star Wars-ed" out now, though.
