The thing that always irritates me is the terminology they use for it: "Full Screen." In actuality, it's not "Full Screen" for everyone, so it shouldn't be used in that manner. The term that I use is "Pan and Scan" or, more appropriately, "Butchered."
For anyone that wants a really easy way to explain the difference to people who are hellbent on their pan-and-scan hackjobs, on disc 2 of the "Die Hard" 5-star Edition, there is a small feature where they show just how much P/S destroys the composition of a film. In fact, SW.com, around the time AOTC came out on DVD, had their own little photographic demonstration of the process, and how anyone could look at that and still want P/S blows my mind.
Every now and then, Turner Classic Movies (who show classic movies, instead of AMC's approach of "Independence Day" being a classic) shows a between-films explanation with Martin Scorsese and other directors (I'm fairly certain that Sydney Pollack is one of them) about the history of widescreen formats and why P/S destroys filmmaking. Very good stuff.
"I don't like them thar black bars, hurrr." Well, when the US switches over to a fully digital broadcast spectrum and the old 4:3 TVs begin to phase out at retail, I hope the "foolscreen" people have fun saying, "Why are these dang black bars on the sides of the picture now, hurr?"
As for the ROTS DVD itself, I really hope that the documentary on the bonus features disc isn't another "Look at what my computer can do" type of thing. I loved the "Beginning" doc from the TPM DVD, but the "Puppets to Pixels" doc on the AOTC disc was boring after about ten minutes. Yes, you can do amazing things with the computer, Rob Coleman, but the character of Yoda is why people like him, not because Sun Microsystems makes him out of ones and zeroes.
