The problem with Fargo is that there aren't any substantial characters. Everyone, from the overwrought Jerry to the methodical Marge, is a pure caricature. None of these people are particularly interesting or sympathetic, and watching their exploits becomes a detached experience. By the end of the film, you're more interested in how the filmmakers choose to tie together loose ends than whether any particular individual lives or dies. In the past, the Coens have managed to create characters worth caring about; such is not the case here, and it greatly diminishes Fargo's effectiveness.

Born and raised in Minnesota, the Coens know their home state, which accounts for their ability to reflect reality there (which is like unreality for most of the rest of the country). People say things like "You're darn tootin'", "aw, geez," and "what the heck". Knowing how strange the talk of Minnesotans will seem to the rest of the world, the Coens intentionally play it for deadpan comic effect.
