While you cite several important reasons folks like sci-fi, Dr. Who 2, some of us just like the concept of a gentleman who can live about 900 years, have about 8 different personae, own a time machine and travel around the universe with a selection of cute and spunky British teenage girls who generally need a little discipline and training in life's complexities. Scientific speculation is interesting, but I think it will always be the fictional "hook" in the story, the dream or the nightmare, - that's the thing that creates a fan.

Doctor Who was often "light entertainment" as well as television sci fi. A lot of it was just well-loved character actors running to and fro in cramped sets and spouting entertaining dialogue. Some of the better episodes featured clever funky aliens and mind boggling mysteries and what not, like some of the better Twilight Zone episodes, and that's about as much as you can expect from television science fiction. But real science fiction would likely bore most people to death and doesn't have well-endowed women in tight clothing in every scene.
