There's Only One Return, And It Ain't Of The King...It's Of The Jedi

I heard some radio guys pose this question: If you were going to introduce someone to the Star Wars movie series, would you tell them to start with "Star Wars"--which was actually the 4th in the series of six movies, but the 1st one released--or should you start with the very first in the story, and why?

I don't care either way, having seen only the original twice--once when I was 13 and then upon the 20th anniversary, thinking the movie was stupid both times--but I thought the question was interesting. Knock yourselves out...
