Why is JFK so Revered?

There is a thread in LBN concerning most popular presidents and JFK came in at number 1.

Don't get me wrong, I'm not bashing JFK, I just don't understand why he is so highly revered in American society. He was only in office for a couple of years. Did he really make that much of a difference in the roughly 2 years he was in office, or is his popularity more a product of the Camelot mystique, handsome guy with a beautiful wife, assassinated, etc.? I know part of it is that he gave a lot of people hope during the Cold War, but for my money I'd take FDR and all of his accomplishments over JFK.
