I thought it was great. I hope people don't pass it off as a gimmicky "character of the week" episode - it's really not. I think we really learned a lot, and some loose ends were tied up pretty well. I'm glad they used Zahn McClarnon, he really "made" Fargo season 2.

There's some kind of ARG featuring Bernard's brain if you haven't seen it yet. Put the episode clips in order to help Bernie get his memory together. There's no reward for doing it, but it might be fun and I expect it to get more stuff to do as more episodes air.
