This is a great film. It is that simple. The cast are all superb. As is the script, the direction and everything else. It's extremely fuuny in places and is all held together by a great story full of little twists and turns. But it is the characters that kept me hooked. From Buscemi's weasily small-time crook to McDormand's pregnant cop to the guy sweeping his driveway and through every other person you meet along the way, you can see them all as real people. If you haven't seen it, see it. Then watch it again and again.
