It's pretty unique in that for how outlandish and crazy the events are, they're portrayed in an everyday, boring way. You have this crazy caper, people getting shot, kidnapped, shredded... yet the rest of the world just moves along as if nothing is really different.
Frances McDormand's character of ~~sheriff~~ police chief Gunderson is very good at her job, yet it shows as just another mundane daily task to her. She sees all this crazy stuff and just goes back home and goes about her day.
William H. Macy's character is terrible at this plot to earn some money, and instead of pulling the plug, just keeps digging himself deeper and deeper, getting a lot of people killed in the process. And in the end, he just gets snagged at a motel, not a big, long, drawn out manhunt.
I should go watch it again...
