I can see some of what you're saying, but the little unnecessary twists like the plight of the asian woman amused me. There are many forks in the road, and at many of them something very gratuitous and, to me at least, unexpected occurred. The elevator scene is this abrupt escalation that just made me smile reflexively. Like "Yes! Wait, what? Right. Yes!" They're not foreshadowed several episodes out. They're foreshadowed maybe 10 minutes ahead, and the situation could go another way. It would go another way really if this was most other stories, but in Fargo it goes this way. On a long enough run it would become formulaic, tired, predictable, etc. but in 10 episodes I didn't get tired of it.
I know very keenly what it's like to be the only one who gets the reveal before it's revealed though. That's been my experience with most of my family and friends, so if you saw substantially more of it coming than I did then I sympathize. It just kills it when that happens. To me the small quick shifts from normal dysfunctional to hardcore fucked up were a joy to watch.
