The truth is, I really don't care if there are people who actually prefer the prequels...
That's where I've always been too. Fact is, I never give it a moment's thought.
As has already been mentioned; these six people were picked by Lucas specifically to gush over the prequels - the three Star Wars films that always have people apologizing for them and\or defending them.
The prequels don't speak for the franchise. They're just a revisit that, while they made tons of money, failed artistically and were panned mercilessly by critics. The most attention they received was for the software that created them - not for their influence on culture or film, which is none.
That "panel" of Lucas employees gushers is nothing more than marketing.
The fact that Lucas is still trying to spin the prequels speaks volumes.
