From a new review of the film:
Florian Henckel von Donnersmarck's The Lives of Others, now available on DVD, is the best feature film debut by a director since Orson Welles's Citizen Kane. Coming it seemed out of nowhere and defying all the conventional wisdom of the motion picture industry, Donnersmarck achieved a remarkable commercial and critical success with his first full-length film, culminating when it won the Oscar for Best Foreign Picture of 2006.
The Lives of Others fully deserves all the awards it garnered. Evidently a perfectionist, Donnersmarck created a film that is near perfect in every respect. It deals seriously and profoundly with an important but sadly neglected subject—communist tyranny in East Germany—and the screenplay Donnersmarck carefully crafted over several years does full justice to his central theme of injustice.
