ok, deep breath now -
I loved IV & V , the original releases. Stood in the line for 5 hours to see V on its initial weekend. The moment when the line “I am your father” is declared is one of the sharpest memories I have – an over capacity crowd in one of the largest movie theaters in NY all gasped out loud at that second.
VI I thought was fine when there were no ew-oks on screen and I try to forget them as much as possible. As others have noted, to many it felt like marketing placement. I still think NOT killing off Hans was the correct choice.
I was one of the few who liked TPM – with the major exception of the mini-chromosomes. It still leaves me with the shudders of WTFH was that done. Jar-Jar again seemed that a marketing gimmick more than anything else.
The Clone movie did not impress me one or the other. The story was ok, the chemistry between Natalie Portman (who I find very attractive) and
Whats-His-Name was poor, and the direction given to Whats-His-Name was evidently also poor. There should have been much more internal rage showing and the actor has shown he could have done it.
As a reader of Zahn’s Thrace(?) Trilogy, the scene when the clone factory was shown was spectacular – the whole clone factory world was actually pretty good to me.
Then we come to the Sith Revenge movie. I actually enjoyed quite a lot while watching it (I had seen the cartoons so knew the backstory), but 2 minutes after it was over I realized that it really ruins the moment in EMPIRE, it left a lot of holes in the story, had some major points that made no sense and had ruined continuity. Even while watching it struck me how lame the Anakin coversion was.
Worse, and this is to the major point of the OP, the I,II,III seem to be more about marketing than doing the story justice. I feel this way because as it played out, there was no reason for II as a stand alone movie. It could have easily had its first part stuck on to TPM, the middle could have been merged with the story line of the first 2/3 of the cartoon, and then there could have been a potential epic of the last 1/3 of the cartoon and III. But it seems that marketing triumphed over story telling 
ok, end of rant. sorry for being so long.
(now if only a talented group would fill the gap between VI and the Admiral Thrace trilogy … )
