Yes, this film is true to the spirit of the sgraffito writings and thoughts of Proust, but it is impossible for the viewer to follow an account running thousands of pages without familiarity with all or part of it, in addition to a familiarity with the historical context, and overarching that, an ability to sort out the Proustian characters (Odette, Bloch, Charlus, eg) from the real ones (de Noailles, Montesquiou, de Pougy, Croisset, eg) - in essence moving seamlessly with the film in time through Proust's childhood, deathbed dreams, and soirees, sometimes in overlapping narratives, without conscious effort on the viewer's part. Yes.
