Linda sent along a link to this article from Bright Lights Film Journal, which asserts that ROTS is George Lucas’s greatest artistic achievement:
Given the newly expansive potential afforded by digital technology, Lucas is no longer limited to simple filmic references. In Revenge of the Sith, he boldly visualizes his interests in classical mythology and literature; to be sure, the prequels recall the tragedies of Shakespeare, perhaps most evidently in Palpatine’s similarities to Othello’s Iago. However, Lucas digs deeper and further into the past when he depicts Anakin and Obi-Wan Kenobi duelling across the volcanic vistas of Mustafar. When discussing this scene, it is crucial to acknowledge Camille Paglia’s wonderful and laudatory piece in Glittering Images. Indeed, it is in this scene that the film’s awe-striking and unprecedented anachronism totally takes over: painting his images digitally, Lucas taps into our knowledge of Dante, of the legend of Faust, the Christian Hell and the Greek Hades, of the metaphoric burning of Icarus’s wings in the form of Anakin’s smoldering body. Appropriately, John Williams’s score moves further from Korngold-echoing whimsy with each successive prequel, and in Sith it acquires operatic overtones. Never one to divide “high” art from “low,” Lucas draws from every available well of visual representation to craft this uniquely digital genre entertainment, a film that is broadly drawn in its emotional strokes but rigorous in its cinematic grammar.
Go read this from someone who apparently really knows cinema and appreciates it.
