If I wrote a story about an apprentice-wizard farmboy, an old wizard, a princess, a pirate, a dark knight and a talking bear, and there’s a dark castle and a mission to save the princess, the audience reaction to it is going to be based on how well executed the story is, not on how tired people might think the common plot elements are. Done wrong, it’s some bit of horrible pulp that rots on an assistant editor’s floor. Done right, it’s Star Wars.
