Sure, there were some who weren't wholly pleased -- no movie has managed to unanimously please so broad an audience as Star Wars fans -- but the overwhelming response was overwhelmingly positive. Even jaded movie critics who didn't get the previous prequels were won back by the epic tragedy of Episode III.
1. They used "overwhelming" twice in the same sentence.
2. Those dirty ol' critics just didn't "get" the other prequels!
3. The "epic tragedy" of Episode III. Ya know, I believe my English teacher defined Shakespeare's Macbeth as an epic tragedy. I can think of a lot of words to describe Episode III, but "epic tragedy" is not among them.
