If it's a subplot to a story, it is important to the main plot, theoretically, as they are intrinsic to one another. Right? The Han and Leia romance in the ESB is probably the only bright spot in that film. Without it the story collapses under the weight of Vader's oppression. It's also a great arc for these two characters. I give much of the credit to Lucas and Kasdan. Ford and Fisher did a nice job, too. I haven't seen romance of that kind in a SW film since, and I would like them to get back to it in the ST. To clarify romance, I mean love, but I also the exciting and mysterious qualities ANH and TESB evoked in a general sense, too. The romance in ROTJ was lackluster, to say the least. Specifically the dialogue and acting. I find the PT romance difficult to watch on all levels. The one great quality of TPM is the absence of such. My one big question though...will we never see Wookiee or Gungan romance? Just think how powerful and moving that would be...O.K. Forget I wrote that.
