The second season of Fargo, like the first (and the movie) is, despite the tag at the beginning of the episodes, a totally made-up story. It is actually a prequel to the season one story, telling the events that Lou Solverson (played by Keith Carradine in season one, and Patrick Wilson in season two) related during one of the scenes in season one, in which he discussed an old case that was as crazy as what was playing out. The season starts off with a member of the Gerhardt crime family (Rye, played by Kieran Culkin) based in Fargo, North Dakota trying to extort a judge in a diner in Luverne, Minnesota (which is nowhere near Fargo). Things get murdery (as they do in the Fargo storylines), and Rye ends up being hit by a car driven by Kirsten Dunst's character, Peggy Blumquist. Things go off the rails from there as the Gerhardts, lead by Jean Smart's character Floyd Gerhardt, try to figure out what happened to Rye, and head off members of the Kansas City mob who are trying to take over in Fargo. And Lou, ends up in the middle of everything.
The show has a great guest and recurring cast, including Ted Danson, Jeffrey Donovan (from Burn Notice), Zahn McClarnon who plays a Native American Hitman for the Gerhardts, Jesse Plemons (from Breaking Bad), Bokeem Woodbine, Brad Garrett, Nick Offerman, Rachel Keller, Michael Hogan (from Battlestar), and more, and Bruce Campbell. We also do get cameos from some of the season one actors.
For those who get the Blu-Ray set, the extras include five featurettes; titled "Lou on Lou: A Conversation with Patrick Wilson, Keith Carradine, and Noah Hawley", "Waffles and Bullet Holes: A Return to Sioux Falls", "The Films of Ronald Reagan: Extended Fargo cut", "The True History of Crime in the Midwest", and "Skip Sprang TV Commercial". The commercial is the shortest of them (just under a minute), and the Waffles and Bullet Holes featurette is the longest at just under 45 minutes. So, there is a decent amount for those who like watching the extras.
Overall, the show is good. It does get a bit weird at times, even introducing the hint of aliens. But, it is a good mix of drama and very dry, dark, humor. There is some sexual content and a lot of violence, so like season one, it is not family-friendly. That said, the acting is great and the writing is very good. So, if you were a fan of season one, this is definitely worth watching.
