The history of cinema: one hundred years of do-overs. Whether updating critically acclaimed foreign hits for Hollywood consumption (Seven Samurai became The Magnificent Seven), bringing the art house to the grind house (The Last House on the Left was a gorier iteration of The Virgin Spring), or reconstituting old plots as inspiration for new genres (Star Wars was based on The Hidden Fortress) or showcases for newfangled effects (The Blob was reincarnated as . . . The Blob), the remakers keep on trying—but the films will never be as good as these originals.
