I didn't see a thread on this. The wife and I watched it last night. While not a great film, the premise is interesting. Offerman gives a good performance. In a different life, I practiced criminal law and would see these Sovereign Citizens come into court from time to time. The judge, clerks, and prosecutors would all let out a collective groan when they launched into their "legal fiction" and "I'm the administer" spiels. I tended to just sit back and enjoy the show. The film lays out the character type that subscribes to these ideals well. But, it felt like the film itself lacked cohesion and direction. Still, if you're interested in this very real subsection of people, it is worth your 100 minutes.
Life's an endless party, not a punch card.
