We caused some consternation last week when we said Danny Boyle might be the most gifted director currently working in science fiction. So it's time to settle the issue. Who's really the greatest and most talented director creating science fiction movies today? Note: We didn't include any directors who haven't worked in the genre this decade. We also left out McG and Brett Ratner. If either of those guys is your favorite director, we're very sorry. Very, very sorry.
