I think you are both missing the point, liz and hp. A movie with a plot...not exactly the most complex of dramas or comedy I might add, is something that is still composed of scenes that can be returned to, but are framed in such a way that an atmosphere is created that excites the customer, rather than a flatbacked person getting it in a stand alone scene. The ADD thing still applies, because they will nut it, but will return to the film...again and again until the plot goes stale.
Here is an example....click the Abigail Fraser trailer...
