I don't think there was any way to save the "surprises" in the OT when the PT got made. It just wasn't possible. An unfortunate by product of making the PT, that's all. it does suck, but what can ya do really.

I do agree that the trilogies should have been more seperate. No droids in the prequels, things wrapped up between 3 and 4 a little neater, etc. There was too many loose ends between the trilogies. I don't think they are connected all that well. Lucas seemed to do it in a way that felt more out of obligation that for the sake of story flow.

Then again, I may not know what I'm talking about here. The whole thing just feels wrong now, that's all.
