Dude if you saw someone acting like that you wouldn't think "oh he's hung over" you'd call a fucking ambulance. I can suspend my disbelief but the idea that his wife, strangers, friends, and co-workers all treat him as if he's just having a bit of an off-day is insane.
This season so far is like 70% a test of patience. People falling over themselves to praise this, "Lynch is blowing my mind" - with WHAT? Making an extremely slow show that's a lot of plot setup with hardly any direction? Awesome, great. I'm sure it will all click into place at some point but the only amazing thing about this show so far is that people have convinced themselves that it's genuinely amazing up to this point.
As a person who actually studied film and film theory and somehow managed to get a degree for it, I humbly suggest that you have no idea what you are talking about.
You are wrongly holding onto details of the plot as if it matters...you think its weird that Coop is being ignored? Have you considered that perhaps Lynch is trying to tell you something about Dougie and his relationship with his wife and his so-called friends? Perhaps we are seeing something from a particular point of view? Perhaps its a dream?
None of things means anything to me yet but it doesn't really matter because with Lynch, it's NEVER about the destination but about the journey. In modern times, where binge-watching is a thing, the desire to get to to next plot point is of utmost importance so a show like Twin Peaks can seem to drag and I get it. It does takes a bit of "reprogramming" to get used to his style but (and I can't stress this enough) it's sooooo worth it. Every scene is dripping in double meanings...the color of clothing, the random stuff in the background (did you notice the red balloon in the house with the junkie mother?). For newcomers, this may come off as pretentious but I would suggest that they are simply unaccustomed to seeing actual, honest-to-God originality.
If you are interested in sticking through the journey, I suggest that you absorb it and not try to make sense of it. That will happen in time...enjoy the trip. The random plot moments will resolve themselves in time...in the meantime, try not to set your expectations as the goal to be achieved and you will be much happier
Note: I rambled above...sorry! I'm at work and I kept coming back to this post to write some more and I think it may be a bit disconnected. I just really love Lynch and this show has (for me) been an absolutely amazing and I just want others to share in it. Take care!
