Confused and single-paced. Too long spent in '12 Angry Menesque' rooms. Unable to reconcile coherently or convincingly private/public, hero/villain, subjective/objective conflicts/perspectives. Endless glowering expressions unbalanced by a couple of naked scenes, with slighty too obvious and bizarre 'climax' as 'sanskrit destroyer' as opposed to 'creator of life' conclusions... If 'ethics' are the thing, we should not escape/avoid the visceral reality of what happened in Japan, yet there is only a verbal description and the news of the atomic bombing arriving over the phone. While this stays true to the film's focus on its protagonist, it hardly makes for compulsive viewing. It would be like making a film about D Day while staying on a peaceful English beach. Nolan should have watched 'The Dam Busters' on how to balance homefront science with wartime consequences.
