This movie has such a great tone. It's moody without being overly so. It's swift and easy going, while also containing a slow boil and brilliant atmosphere.
From Joel Coen's wonderful direction to their equally wonderful way with words, to the beautiful piano laced score, the small little background details and ways the actors play off each other, to managing to be intense and shocking using as little as possible (a sequence involving a shovel was the most intense I've been watching something in awhile).
It's amazing to me that a movie this good was their first, but then again, they are two of the best filmmakers working, so I shouldn't be that surprised.
Plus, it's always the sign of a great film that as soon as it was over, it felt like it had only started and I was more than willing to watch it again.
