dull cinematography!
While the movie develops some interesting characters, the cinematography underscores what is problematic about this film: it's too talky. Long monologues and speechifying.
The movie's cinematography makes the worst of these speeches, having you watch the speaker over the shoulders of the listener. Rarely do you see how the listener is responding to the speaker, until they reverse positions, and now you look over the shoulders of the other party. Why not focus upon how their words are affecting the listener? Why not dwell on how their hopes are disappointed, their expectations raised or lowered?
