I punched in 1972 and there were some fantastic movies that year (The Godfather, Deliverance, Cabaret, Solaris, Jeremiah Johnson, Aguirre - the Wrath of God, The Last House on the Left, Silent Running, The Heartbreak Kid, Fat City, etc.).

Also tried 1973 — same (The Day of the Jackal, Soylent Green, Westworld, The Wicker Man, Papillon, American Graffiti, The Sting, Serpico, Mean Streets, High Plains Drifter, Don't Look Now, Badlands, The Long Goodbye, Jesus Christ Superstar, The Three Musketeers, Fantastic Planet, etc.).

I think they simply made better movies decades ago.
