I'm not watching the series as I saw the original film and din't like it. But I thought I would mention another film called "A Simple Plan" which was made a couple of years later. There are some similarities between Fargo, the film, and A Simple Plan with both about how money can be a corrupting influence. Also both films make exceptional use of snowy landscapes of northern states in the USA
Also Billy Bob Thornton was in A Simple Plan and was nominated for the Oscar for Best Supporting Actor.
It's a very good film, and I rate it as the best film of the 90s that I've seen.
