The fireworks scene is the one scene that left my mouth gaping at the cinematography -- it's just so well done, with the fireworks as a metaphor for Ennis' inner rage exploding to the surface. I tried to imagine how difficult it would be to time the action to be exactly right. And then, when Ennis looks back to his family with a little shame for his temper, and Alma is looking back, sheepish and scared -- the shot is beautifully composed, with so many emotions running through it. It's over so quickly, but it's very powerful.
