Where do we go from here? My second review of OUATIH.

Rating: 9/10 (14 August 2019)

My second review. Perhaps I was overly summarizing in the first one. The point is, I took it for granted that there was no necessity to say anything about the plot itself or point out which parts of other people's reviews I agree with.
I agree with most of the reviews with 9 stars. A "10" would mean one of the greatest movies of all times, which OUATIH is not (yet).
The plot:
Rick Dalton is a "has been" B-star.
Cliff Booth is a "has been" shadow of a B-star.
Sharon Tate is an angel with seemingly bright future. She is the next hottest thing in town (that is, after her husband).
Therefore, Rick and Cliff represent the past, a wish for "Status Quo Anthem". Sharon represents a possible future. However, "the hippies" out there represent another possible future, or at least a pivot point for such to happen. Sharon is another pivot point in these temporal-spatial coordinates.
As we know from history, the Manson pivot point prevailed, and we are living in a 2019 reality as it is. If, on the other hand, the other pivot point would've won (as described in the movie itself), we would, perhaps, live in a completely different 2019 - perhaps more alike to 1969?
Probably not. However you look at hypothetical mind games about alternate realities (histories), there is an element of continuity, saying that the course of predetermined history will correct itself "back in line" despite individual interruptions, then again, some claim, that the "pivot elements" can really change the way the history goes, and the main problem is to pinpoint such "pivot elements", as for the present and for the future such is impossible, but for the past they are not distinguishable enough.
Then we have some multiverse theories, saying, that the timelines split all the time into multi-realities (universes), that exist in parallel. I find the latter theory the farthest off, as we have no way of observing, recording, or moving between these universes, if they exist.
The important thing in all these observances is, that it doesn't make any sense to further complicate the above concepts, as then they become even theoretically untraceable, i.e. we shouldn't use multiple "what-if" set-ups upon the same framework, or we run a risk of a total loss of any coherence. (Example: "the hippies" should not be unsuccessful and successful at the same time and Sharon should not be alive and dead at the same time, and Rick should not go down and up at the same time - if we sum up all these propositions upon the same timeline, we result in what can be called "un-collapsed" wave function everywhere.) But all this, I believe, is slightly beside the point.
The point being, who or what are the exact pivot elements in 1969' LA, who (or what) are they directly influenced (orchestrated) by, and by which degrees of force (accuracy etc.) did this elements actually cause a deviation in the timeline from that point, meaning: did they actually de-track a predetermined timeline or not, and, of course, the same goes for alternative pivot timelines, resulting in what might have caused a totally alternate course of history.
A history in which Sharon Tate would have lived and prospered.
A history in which the 1960s never ended, the 1970s never happened. A history in which there would be no need for QT. And a history in which we would not watch with wonder in 2019, what "otherworldly" 1969 QT dares to present to us, as such world would not be as far removed from ours, as it actually is.
Another thing: Once Upon a Time in Hollywood reminds me, more and more, on Mulholland Drive, not only for the obvious reasons.
OUATIH feels, after a couple of viewings, like one of those "lucid" dreams, where the dreamed reality resembles the actual reality to a degree, that it is believable and undistinguishable from the latter. A dream, that has sequels, just as the waking reality does. To a degree, that while in one of either "stories", you are not aware of the other timeline, although, obviously only one reality seems to be the one we always return to (guaranteed), while the other timelines come and go and may have the "next chapter" only else-when, or even not.
Therefore, in the same way that the two realities presented in MD converge and diverge at the same time (albeit in different movie-timeline directions), in OUATIH we have just the "dream" reality and no "real" reality, therefore we are probably invited and allowed to - just dream on...
...which, in my opinion, really transcends anything we have seen by QT before.
Thank you for your attention!
