In the end people remember good movies. Bad movies fade away.
That's why people always talk about the Golden Days of Hollywood. People remember "Casablanca" not "Shhh Beware the Octopus!"
People still look at Bela Lugosi's Dracula as the icon. Some film enthusiasts recall the lesser later movies in the Universal Monster series. Star Wars will be much the same way.
They could package the blu-ray of Dracula with a picture of Abbot and Costello on the front, but in the end people will remember Lugosi.
