I'm not watching Fargo, the TV series. I was somewhat interested. I liked the movie and I'd read enough about the TV interpretation that I was pretty confident it wasn't going to be a weak re-hash of what was already done so well in the movie.
I hadn't read anything about the cast though, so when I first saw Martin Freeman, I said "Hey! That's Martin Freeman!".
And, for a second, I was excited about this series. Then Martin Freeman started talking in that Minnesotan accent made so famous by William H. Macy and Frances McDormand. Oh jeez, yah, eh? And I was no longer excited. I can accept Martin Freeman as any kind of Briton and even a hobbit but he is no mid-westerner.
