It's fun to sit down with my son and watch the old science fiction TV shows and movies. I've successfully got him hooked onto Star Trek (and he informs me that Deep Space 9 is his favorite series from the franchise). We've binge-watched Farscape (by far one of the best science fiction shows… so funny). We've had discussions about Battlestar Galactica, admiring how the various way the 2004 series pays homage to the original 1978 series. And when he's home on holiday, we've been diving into Babylon 5.
I've successfully convinced him that Firefly should have never been taken off the air when it was, and we both agree that the psychedelic trip into the monolith at the end of 2001: A Space Odyssey is just a "WTF?" moment. (But seeing the original gave him an extra level of appreciation when Farscape did their parody scene.)
During our binge watching of old TV shows, he's been laughing at the absurdity of the situations (and how the writers got away with a lot of things that they would never be able to get away with today). But it's the inaccuracies of the past timelines for the show that gets him the most. How wrong did fiction get their predictions for reality? Whenever he gets incredibly cynical, my response seems to always be the same.
Before you start to criticize the science fiction of old, highlighting how wrong they got the predictions, take a look at the real history and the trajectory that we were on when those books were written and when the films and TV shows were filmed.
