Like Memento and indeed Mulholland Dr., Inception has generated a big debate over multiple meanings and plot interpretations, with many theories abounding about what is *really* going on. This was Nolan's intention, of course, and it's added another facet to the film's already considerable success. Naturally absorbing such theories creates an impetus to see it again, or to get the disc asap. Art and commerce have found a new fusion.
