It makes sense that actors on real sets deliver better performances, and the more real things you have on set thats real, the more the actors can react to and play off of. Just think of Star Wars... synthetic sets... synthetic props... digital creatures... God do I feel for those actors.

oh yeah the last line of episode 3-- Darth vader bows before the emperor in his throne room, and says "What is thy bidding, my master?" Play the dark side theme very loudly with Cellos which swells into the Star wars theme for the end credits.
