Movies that are filmed in widescreen should be shown in widescreen. I don't mind pan and scan as much if it's used for a light comedy like, oh say, jay and silent bob, but for the most part it bugs me. You miss a full 1/3 of the movie! You might think "oh, it's just the sides, it doesn't matter" but it does. Directors convey a lot of information using the frame, and pan and scan just totally slaughters that. Of course, using widescreen for the sake of widescreen is even worse, there's really no reason to have the black bars on shows like ER, it just adds some fake element of drama (IE, people associate widescreen with drama, they see the bars and belive that what they are seeing is somehow more dramatic).
