Insert EpIV "Revisited", and all of a sudden you can almost buy that this is a continuation within the same saga. Better picture quality, larger scale Imperial fleet, aliens that aren't plastic muppets, an almost respectable duel between Obi-wan and Vader, laser blasts that actually hit people and look like laser blasts, much better Death Star and ship graphic readouts, light sabers that aren't toothpick thin, and an epic battle at the end that is Star Wars worthy, not to mention explosions that look realistic, and Chewie getting a medal.
Aside from that the original or SE is a great movie on it's own, and will always have that nostalgic childhood memory thing, but for me Revisited has finally bridged the two trilogies together, and truely helped to create a believable saga.
Peace....
