A unique plot can make a story memorable. For instance, in 'Inception', the idea of entering dreams within dreams was so novel. Also, the setting can be crucial. A story set in a post - apocalyptic world like 'The Road' creates a vivid and memorable backdrop.
Themes play a big role in making a story memorable. Take '1984' for example. Its themes of totalitarianism, surveillance, and loss of freedom are so relevant and thought - provoking that it sticks in our minds. And the way the story is told, whether it's through a first - person narrative like in 'The Catcher in the Rye' or a multi - perspective one, also affects how memorable it is.
Characters make a story memorable. If the characters are well - developed, like Harry Potter, we remember them. Their traits, dreams, and flaws stay with us.
