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.
