Star Wars is adolescent nonsense; Close Encounters is obscurist drivel; ‘Star Trek’ can turn your brains into puree of bat guano; and the greatest science fiction series of all time is Doctor Who! And I'll take you all on, one-by-one or all in a bunch to back it up!

When you're all alone out there, on the end of the typewriter, with each new story a new appraisal by the world of whether you can still get it up or not, arrogance and self-esteem and deep breathing are all you have. It often looks like egomania. I assure you it's the bold coverup of the absolutely terrified.
