A science-fiction author scours the new "Star Wars" film for signs of intelligent life: First off, let me say that I think the film looks gorgeous. George Lucas was able to hire the best. He took advantage of advances in computer graphics to portray many old sci-fi favorites in vivid ways. The costumes are just spiffy, the sword fight scenes zesty. Great aliens, too (except for Yoda, who’s still a rubber oven mitt with two facial expressions: patronizing and condescending).
