I saw Star Wars in the summer of 1977.
I thought it was a good movie. Lots of action. Nice special effects, especially when they went to hyperdrive or warp speed, whatever they called it. And blowing up the Death Star was exciting.
I didn’t, however, think it was excellent science fiction.
It was basically a western or war movie in space. Even the starships looked like WWII destroyers or battleships rather than flying saucers.
Still, it was a great movie that begot others in its lineage.
But on this holiest of holidays in Star Wars Universe, I thought I would recommend some really excellent science fiction novels and/or movies.
2001 A Space Odyssey
The Adventures Of Superman (It’s just my favorite all-time TV show.)
The Time Machine
The Illustrated Man
The Andromeda Strain
The Lathe Of Heaven
Star Trek (The Original Series)
This Island Earth
The Day The Earth Stood Still
When Worlds Collide
It Came From Outer Space
World Without End
The last five on the list are typical 1950s vintage science fiction, but they each have a good storyline even if the special effects are slightly lacking.
It is the storyline for all of the above that separates them from Star Wars. Where Star Wars had no relationship or lesson for Planet Earth, the list I have selected all have Earth-born characters or actually take place on Earth.
Other Sci-Fi that, to my knowledge, have not been portrayed on film are:
Childhoods End. Arthur C. Clarke
The Foundation Series Isaac Asimov
Out of the Silent Planet (and companions to his trilogy.) C.S. Lewis
The Ender Series Orson Scott Card
Obviously, like my music lists, it is all a matter of taste.
I would be interested in hearing what your favorite science fiction stories/movies are.
