Why do we make comparisons? "Godfather like", "Taxi Driver kind of approach", "somewhat like Casablanca" and so on? (we don't hear "like Franz Liszt Consolation #3" or "similar to Beethoven Symphony #9"). Doubtless, these references and inferences are precious to a newbie on the climb up the stairs. But does it make it easier for a writer to quote a previous memorable creation, when the obvious ask comes up-mostly at the pitch?
