Revenge of the Sith is simply outstanding. I've been waiting for this movie my entire adult life. Star Wars has permeated everything. It is our mythology. After reading Kevin Smith's review a few weeks ago I started to get excited again. The critics have been incredibly positive, and they usually don't get science fiction. I skipped school (easier when you're the teacher) & we went to the noon showing. It was well worth it. I haven't stopped smiling all day.
