Joking aside, ATONEMENT's technical merits far surpass those of its narrative, which despite offering a superb first half, eventually begins to wane somewhat once the backdrop changes. Whereas the film's later scenes feel mostly like a necessity to progress to the gut-punch of a twist ending (which some viewers may love, or others may despise), the early sequences deliver a stellar balance of crafty filmmaking and strong character delivery. Some of the most effective stylistic traits include alternating POV's of the three characters and the use of typewriter sound effects to act as a sort of percussion for the phenomenal score.
With so many cool elements being put into effect, I often found the film to be alluring even when the story had little of interest to offer, such as with the gorgeously filmed single-take shot with McAvoy traversing the beach during wartime. So if you appreciate the art of filmmaking, and are in the mood for a rather different type of period piece, ATONEMENT makes for a worthy viewing, even if it's not necessarily as amazing as everybody has made it out to be.
Commentary (with director Joe Wright): On a scale of "interesting" to "boring," this track should score equal to that of your thoughts on the movie.
Bringing the Past to Life: The Making of Atonement (26:00): Insightful and loaded with interviews.
From Novel To Screen: Adapting a Classic (5:00): Far too short to be fully enlightening.
Deleted Scenes (7:30 - with optional commentary): Rightfully excised scenes. They would've slowed down the pace.
