I kinda like the idea of Twin Peaks dealing with the idea of modernity. Though I don't really have any fully formed notions about the concept.
I understand the concept that Twin Peaks has always had something evil in the woods.
What I will say is that one of the big drivers of all the horror at this particular point seems to be all the drugs that are being handed around in the background. Cocaine is a huge plot point in the movie. At the point TP aired, I think the drug trade in a small town might have actually been a little "laughable?" Especially because they picked Cocaine which is imported not produced in a place like Twin Peaks. What I am trying to say, is that this was a time before many of the people in larger cities (or even medium) ones realized that, like the prohibition era and alcohol, a lot of drugs like marijuana, meth, and mdma were actually being made in small towns. These were small out of the way places that benefited from having too small a police force to be up on it or were in some instances complicit in their production. I don't know what I am saying here in any concrete way, but I definitely like the idea of the town having to deal with the War on Drugs and how that lets the modern world knock on their door.
There is also the notion of the "outside investors" for the hotel being a threat to their current way of life.
Maybe this has something to do with the mixing of the old evils and the new evils and how you don't want that to happen in a place like Twin Peaks. I have always felt that in Twin Peaks evil is a currency worth more to than in other places, if that makes any sense.
