Ah, I can't believe I someone didn't already mention (Coen Bros. masterpiece) "Fargo." Many people here in Minnesota thought the accents were a little much, but they're only slightly exagerated. People do still talk like that up north, with many variations (the Finnish-Minnesotan accent is my favourite). But having the Lundegaards and other people from "the cities" speak with it, while funny, wasn't really accurate. Unless they just fell off the truck or something, very few people under 80 would be caught dead with that accent down here. Minneapolis and St.Paul have their own unique accents (which have always sort of reminded me of a weak, Nordicised Chicago accent, but maybe it's just me), though most people here, as in many places around the country, speak with a generic "news anchor" accent. (I speak with a slurred, lisping news anchor accent, myself)

Just my opions, of course. :)
