What I'm saying is, even in that context, I think this might not actually be trying to say anything except one thing, which is an idea I'm beginning to circulate on as I think about it - that you can't return. It seems to be a fundamentally negative expression, right?
... also having the previous world be so almost cruel and bleak we're left with only this - you cannot go back and fix things, everything is just fucked up and grim no matter what.
... in service of what? In service of 'nothing', that's what I mean when I say it might be about nothing.
...
It's almost as if David Lynch just spent 18 hours explaining to us why going back to Twin Peaks is a bad idea - but that isn't a deep point, it's a reaction to the reaction to his own work, it doesn't say anything outside of itself, so it becomes this recursive and honestly just kind of self-obsessed nonsensical loop that doesn't actually want to be engaging. In fact it wants the opposite.
There comes a point where 'you don't get it man' stops holding weight. If there was a theme to this, some central thing I'm overlooking that actually imbues all of these events with some kind of meaning, then people would be more forthright about it.
I've certainly been forthright about what I think gave it meaning, even in response to your own posts. Ultimately it's abstract art, so not everyone will be on its wavelength, those who feel they are won't be on the same page, and it will take a while for anything close to a consensus to solidify.
That said.
While Lynch is expressing the idea that you can't return to Twin Peaks, the 25+ year old work, he has not created a self-obsessed wank that says nothing outside of itself. The metafictional commentary is ultimately a minor aspect of the entire message, that we cannot return to the past. It is applicable to real life in profound ways. Dale Cooper dooms himself by denying the present reality in trying to 'undo' that which cannot be undone. He is stuck in the denial phase. It is about the necessity of confronting pain head on, and the way repressing your trauma comes to bite you back. Laura's scream at not being able to suppress the trauma of her own abuse within that house, and Audrey's scream at being reminded of her own past and identity as a rape victim, are all a reflection of this. We can't escape our suffering unless we're willing to take the first step of admitting to ourselves that we suffer.
And even if we are not so haunted by trauma, we can still take the message of the danger of not admitting to ourselves what our actions are really accomplishing. So many people hurt themselves in the long run by not admitting the ultimate fruitlessness of the path they choose in life. Happiness eludes us, like Richard/Cooper and Bad Cooper, who are so obsessed with their idea that they'll find satisfaction if they follow their path to completion that they're unable to enjoy the moment along the way. As long as they chase an unreachable goal, happiness will be out of their grasp.
It's not ultimately a negative message because while we're shown the tragedy of those who can't escape their fate, we're also given the positive examples to show there's another way. Jerry and Jacobi are weirdos in the eyes of society, but they're ultimately enjoying life. They've found a way not to be bothered. They're not harming anyone, so it's not necessary to care about trivial matters like what anyone else thinks. Those who get it, like Nadine, get it, those who don't, don't. Or Carl Rodd, who despite having 'already been places' that elicit a dead eyed stare, is still finding a way to enjoy life. He witnesses suffering all around him, but rather than hide from trauma, he confronts it head on, and tries to help those who suffer, even if it means having to take on a little of their pain on his shoulders. He's found an authentic way to live, and he still takes time to enjoy the moment, gazing at the beauty of the trees or playing his banjo.
Finally we have Dougie Cooper. Dougie, now fully awake as he heads through the red door, is a Cooper that has learned an important lesson that our Special Agent never could. Rather than getting trapped by the past, letting its trauma cloud his head to the extent that he never feels happiness, he chooses to live in the moment. He doesn't take his blessings for granted. He accepts the love of his wife and son, whereas Agent Cooper drives away his lover by being unable to be in the moment with her - he lets the darkness of the past cloud over where once there was love, in that tragic sex scene. And then, she's gone, before he realised how important what he had was.
It's a message about the need to enjoy life, despite the sadness. The importance of accepting the present moment and making the most of it, and the futility of letting the pain of the past prevent us from enjoying the rest of our life on earth. It's a tragedy that gives us examples to hopefully guide the audience to a better life. Therefore, it's far from recursive self-obsession, but a work of art designed to give energy and life back to the world.
