That's a good point. At the same time, though, I think they could have done a better job paralleling the overall struggle with Luke's personal journey. I thought that the PT did a great job in terms of this by reflecting what was happening to Anakin with the Republic itself. I was also more invested in the Republic storyline and so it really hit me hard, along with Padmé, when it crumbled. The Rebellion conflict just seems too static for me really to invest in and it's a shame because Han and Leia are primarily defined through their ties to the Rebellion which means I tend to find them unengaging.
