"The Gernsback Continuum" makes a regular appearance in my COMM 149 classes - sometimes to the consternation of my students who struggle to wrangle with the author's rat-a-tat pop culture references and full-tilt plunge into weirdness.
Never read the story? I recommend that you start there. Afterward you might check out the BBC's version. Doing it the other way around - or, God forbid, limiting your exposure to the video - would be like dismissing the need to read The Great Gatsby because the movie is available at Blockbuster [Ooops, I'm dating myself. I mean Netflix].
And, no, Gibson's short story isn't "great literature," but it's certainly worth a read. Then a look.
