As someone who accidentally watched the "Before the Law" episode of Fargo first (my DVR ate the pilot, and I didn't realize), I can attest to its status as a good point of entry into the world of Fargo. I had a whole lot of questions, and was surprised that I hadn't heard anything about what I thought to be the in medias res structure of the season, but I was totally intrigued by the tone and the characters and the woodchipper homage. (Once I realized my mistake - thanks to reading a recap of the first episode that was completely different from *my* first episode - I went back and watched the pilot and many of my questions were answered. Engaging with linear stories in linear order is generally a good idea.)
