Normally, I hate these kinds of endings, but this one didn't bother me. I like that it's a litmus test: what kind of person are you? What do you think the world is, at its core? A flawed place genuinely trying to do good, where real justice still takes place, or a rigged game from top-to-bottom?
I didn't notice the clock thing; you're certain it was five minutes? If so, that's a very nice, subtle method of having it both ways, of giving us our little hero's victory while simultaneously asking the question above.
I don't mind the Swango stuff at the end: she didn't do what she was supposed to. It was kind of shocking when she shot the police officer, until I remembered she was pretty darn shady in the first half of the season. Easy to forget she wasn't good, she was just in mourning, and just making trouble for someone we hated more.
I also don't mind her and Wrench outsmarting Varga's crew. I think of it as:
1) She wasn't as small-time as she seemed. The bridge stuff suggested untapped potential.
2) Wrench isn't really a petty criminal. He's very skilled, as we've seen in past seasons.
3) Varga was overconfident. He seemed calm and scary because he was in control. But lots of people seem that way in control, and it falls apart the moment they're not. EDIT: oh, and he's down a man or two, I believe.
Anyway, really thought the last couple of episodes pulled this season together pretty well. And I like how increasingly weird it was at times. Still the "worst" of the three, but I think that might have more to do with how similar in tone they all have to be in order to still feel like
Fargo. I'd like to see more, but it wouldn't shock me if we've seen the best (or even the last) of this show. It was such an odd thing to try at all, and so delightful that it ever worked, let alone so well.
