Finding good science fiction can feel nearly impossible with today’s market flooded with sequels and reboots. That’s why you should look back to the 1970s, when movies took genuine risks without needing massive budgets. Can you believe “Dark Star” turned space travel into brilliant dark comedy for just $60,000? Meanwhile, films like “Colossus: The Forbin Project” were already warning us about AI dangers a half-century before our current tech anxieties. Instead of relying on fancy effects, these movies solved storytelling problems through clever writing and innovative techniques.
Give these classics another look, and I promise they’ll completely change how you see modern sci-fi.
