Film is a visual medium, and not just a still visual medium, so simply seeing screen caps won't make any difference either. And the special editions sometimes even ruin the pacing as well. I watched Empire on DVD yesterday, and since that is one part of the 2/3rds of the original trilogy you haven't seen, then it'll make a good example. Even before I turned on the SEs, I always thought that the Vader going back to the Executor was a dumb addition. And when I watched it the other day, I was immediately reminded why. First and foremost, it's just completely unncecessary. Second, the shuttle scenes replace actual important scenes of Luke being rescued. And, finally, what I'm getting at... the Falcon speeds away from Cloud City, persued by several TIE Fighters, and then...! Everything stops, and we sit around for 20 seconds to watch Darth Vader walk off his shuttle. Totally ruins the pacing. That's the kind of thing you actually need to see. Everything just flows so much better.
