I finally caught up with Star Wars III last weekend, and, yes, it was very excellent, spoiled only by the unintentionally funny dialogue.
In fact, the best part of the entire film comes in the final minutes when Darth Vader discovers the worst about his transformation to the Dark Side and cries out "NOOOOOOOOOOO!", to which I pissed myself laughing.
So - and this, I have found, has worked well in Another Place - what is it that makes Darth say "NOOOOOOOOOOO!"?
Here's one to start you off. Suggest-me-up!
"And another thing - we found your stash of gay Bantha porn on Tatooine"
