I didn't really like TRAINING DAY, because it has a message that seems dangerous if you generalize too much to groups of people. But I liked the acting and it has an attractive story structure. It works according Aristotle's requirements of drama, in having unity of action, time and place--with everything happening in a singe day within the world of these two characters. And I like those stories where you start on the outside and move steadily inward--discovering things with the main character (Ethan Hawke). In that way it's a lot like HEART OF DARKNESS.
