I watched "Tread" too and thought it was pretty even handed.
And as usual, the truth was probably somewhere in between. I got the impression that the town's "good ol boy network" did mess with him, (It's not as if anybody would admit to it on video) but OTOH, there were pretty clear regulations about easements and sewer service etc. and he could have tied in a lot cheaper to the new lateral when the next plot over got developed. And from his own tapes, it was clear Heemeyer was definitely just plain nuts.
And considering he sold the business/plot of land and it's buildings for several times more than what he paid for it, it doesn't seem like he got an unfair deal at the end.
What I found interesting from a pragmatic standpoint is that much like a car chase, if the tires don't give out, it's inevitably the cooling system that dies or overloads. So if you're going on a bulldozer rampage, besides good intel on which structures have a basement, upgrade the cooling system.
