Last night, I watched the original version of ANH (er, SW, as it were). I've only seen it once before, and it was, I think, in the summer of 2004.
Anyway, in the cantina scene, I was expecting to actually SEE Han shooting Greedo and not have Greedo even get a shot off, due to the fact that everyone's been b*tching about showing Greedo shoot. I didn't remember that it was only a big confusing puff of smoke. The way people have been complaining about it for the past nine years made it seem that it was absolutely, 100% clear that Greedo never shot (or shot slightly after Han) in the originals.
Personally I don't care whether Greedo or Han shot first; I'm just glad that you can actually see the shooting at each other in the new version. Plus, now that the terrible-looking old version is on DVD, people can just watch that one and shut up about it.
