At first, the flourishes of Mamet's dialogue feel somewhat at odds with Corrente's naturalistic direction, but as the story reaches its halfway point, and the story's theme of inertia and misunderstanding becomes clearer, the gulf between what's being said and how the actors are saying them only adds to the film's impact.
If you enjoy "Mamet-speak", you'll like this filmic adaptation of the play. All three actors not only play the rhythms, they transmute the verbal ping-pong into beats at the heart of their friendships. It's a film given over entirely to the writer and actors; no directorial flourishes here. None needed.
