Before “Robots” started, the extended trailer for “Star Wars Episode III: Revenge of the Sith” debuted. This is a big event for geeks everywhere. Many feel that George Lucas has royally screwed up the new trilogy, but this trailer should bring hope to some of them. The trailer emphasizes the darkness of the third film, when Anakin finally falls to the dark side. It looks like Lucas isn’t pulling any punches; we see Anakin kill several people in the trailer alone. Lucas has, in several interviews, advised parents not to bring their children to see the new “Star Wars,” and has predicted that it will be the least liked of the series. After the childish “Episode I” and the angst-ridden, adolescent “Episode II,” perhaps with “Episode III” the trilogy will reach adulthood.
