This movie is still great but I feel the show, specifically season 1, built on the themes and ideas of this movie fantastically and improves them. The movie has less time to develop everything it's trying to do but it's difficult to compare it to anything else because of how unique it is. Pulp Fiction is a thriller that we could compare, an id rather watch that most times. Where the movie Fargo excels at is being small; the characters, the story, etc. It's grounded and realistic, unlike some aspects of the show. If you haven't seen the show yet I would recommend trying the movie out first to see the developed between it and the show.
