I really liked it, but I recognize its limitations. However, I wouldn't speak of mannerism or aesthetic flourishes for their own sake. Rather, there’s a lot of courage and a desire to experiment with new solutions: Lynch, fresh from his divorce and completely free (his wife was his editor and always pushed for the "normalization" of her husband's art), made a film for himself, a true artist's experiment, chasing his visions and disregarding how it would be received by the audience. Consequently, his detractors have one more reason to hate him, and perhaps this time even some of his fans have wavered.
Certainly, Lynch lost something, especially in terms of formal elegance. Moreover, the fact that the film went crazy from the beginning resulted in a lack of the tension that, for instance, was present in Mulholland Dr., where the elements get scrambled in the final act. Instead, right from the start, abandonment and passivity prevailed amidst the bombardment of nonsensical scenes. And the renunciation of any attempt at understanding actually diminished the pathos. Thus, all we could do was follow the events with unhealthy curiosity, and for that reason, I managed not to get bored for three hours (which is no small feat!).
I watched it a second time and I have to say that I understood even less than the first (indeed, with a more attentive eye, the plots thicken instead of simplifying), but from what I grasped the film was inspired by Laura Dern's monologue and then constructed progressively, so it's also pointless to strain too much in understanding its architecture and cinematic mechanism ("I saw dogs reflecting": perhaps he was referring to the audience).
It's also worth considering the possibility of mockery (the Fellinian reference could be a clue), but that does nothing to diminish the film's expressive power. For while Lynch has certainly lost something, it must be said that he gained something else: this time he truly went beyond, creating the most extreme film of his career and perhaps of cinema as a whole (speaking of mainstream), he demonstrated courage and the strength to change. A stream of consciousness that could compete with Joyce's (and even the great Joyce is not an easy or pleasant read... a matter of taste).
The choice of digital also didn’t disappoint me; it added sickness and morbidness to the whole, and there were indeed scenes that really struck me: like the outdoor barbecue... I found it so idiotic and at the same time surreal that it even unsettled me.
The bunnies were beautiful, Laura Dern was fantastic, and the music was lovely as usual. No, in my opinion, Lynch is beyond discussion; with Inland Empire he was a perfect architect of nonsense, as no one else could have been. It made me struggle (damn, those shaky and grainy shots with the handheld camera, tight spaces, close-ups, in the dark... I came out with ten fewer diopters!), that's true, but I wasn't disappointed. To be watched and rewatched and rewatched until blindness sets in...
