1.) the opening: why is the algorithm object stored in an opera house? and why do the ukrainian terrorists want to retrieve the object? (were they hired by sator to retrieve it for him?)
2.) the blackmailed wife: how exactly does sator blackmail his wife with the forged painting? (by damaging her reputation, making it public that she took a forged painting for a real one?)
and why is the painting stored at the oslo fee port (where also the inversion machines happend to be stored?)? what's in it for kat, if the protagonist steals the painting for her? (is it about destroying the evidence that she once misidentified a forged painting?).
4.) the car chase: if the protagonist tries to steal the algorithm object for sator, why does an inverted sator intervene in the car chase?
5.) the algorithm: if the inventor of the algorithm wanted to prevent it from ever being used, why does he send it back in time divided into 9 parts for each power state, instead of simply destroying it?
6.) how does wiping out the past entirely prevent climate change?
7.) time travel: if the machines only invert time, how can people use it as time travel devices, like sator does when he travels to a time in the past when he was most happy with his wife? (let's say this moment was one year ago, does it mean sator inverts himself and has to wait one year to arrive at this past moment? but even then, wouldn't he meet a his wife as an inverted person?!)
A second viewing may help you answer some of those questions, while other questions have no simple explanation like the "why stored in the opera house". Most of these questions will also be filled by reading the entire Plot on Wikipedia: https://en.wikipedia.org/wiki/Tenet_(film)
i already read the plot on wikipedia. so i take it if you have seen the movie and can't answer these questions you're unsure about these points as well after first viewing?
so sator sits on his hands, wearing an oxygen mask all the time, then goes through the turnstile and then joins his wife on the boat for this last happy moment? but wouldn't he meet his other self from the past there?
2) I think you're right- damage her reputation to the point that she couldn't support herself and her son- defeating the goal of being independent. Whether him revealing the painting as a fake would do that or not, I can't say.
3) You have no 3.
4) Sator knows that they will try to take it from him... maybe. In theory, the reverse people start at the end of the chase and know everything that happened during the chase (like protag and Neil trying to get the algorithm for themselves) and so they can change it by reversing and entering the chase from the end. HOWEVER, the movie is keen to point out that "what happened, happened" so there would be only one version of the event- and Protag and Neil never got the chance to reveal their true intentions until after the chase... when Protag is being interrogated/threatened with Kat's death and he tells him things.
5. The inventor wanted it destroyed, but she lost control of it and it was sent back to 2020 by other people.
6. I'm confused about the purpose of the algorithm. If it reverses all entropy, then very bad things happen in the present and the future never happens. Not sure how that helps the future people. And if "what happened, happened" then there's no point in trying to change the past... before they started, they already lost. So... shrug?
7. I don't think it was as long as a year ago. I think a month or so. The good guys also travel inverted back to that time, and it kind of seems like it takes as long to sail to Vietnam (backwards) as it took to get to the right time. Of course, once they all get where/when they're going, the uninvert so they're going forwards again.
I have some questions:
8. Protag was told to find out about an organization named Tenet. By the end of the movie, we know that he is the leader/creator of Tenet. We know the Indian woman worked for Tenet, as well as Neil and Ives. Did Sator also work for Tenet?
9. The stone with the bullets in it... it was brought from...
9. The stone with the bullets in it... it was brought from another place, right? Did they bring the brass in with it too? I know how the bullet "comes out of the stone" and into the barrel, and even how the gunpowder unburns, concentrates and appears in the cap... but the casing jumps off the floor and into the pistol as well- where was the casing before it was caught? Do they need to move the stone with all the brass that belongs to the slugs in the stone?
10. Ives says something about the turnstile near the freeway being the first/only turnstile their team has ever captured. Did they have their own during the finale, which took place a while earlier? Did they make that in the couple reverse months between capturing the freeway one and the finale?
11. Why send the algorithm to Sator just for him to bury it to send it further to the past? Why didn't the future people just send it further back themselves? Or was Sator trying to "activate it"? I'm confused whether they were burying it or activating it at the end. Seems like both?
12. If the past can't be changed, even when you're there (what happened, happened) why bother going back in time at all? Just to "try"? To create an alternate reality, maybe, that you can never experience, appreciate, or even be sure exists?
9. didn't see any casing jumping off the floor. so i don't know, but theoretically yes, they would have to move the stone with all the brass.
10. dunno
11. not sure i understand the question. sator's mission was to get all the algorithm parts, so he can activate it and destroy the world.
12. yes, i think so. the future people don't believe in "what happened, happened". they choose to believe changing the past will have some positive effect.
i think the whole catching-the-bullet-stuff doesn't make any sense at all. in order for the progagonist to catch a reverse bullet, he would have to be reverse himself. you can play the scene in reverse and watch the proganist shoot the bullet in the wall, so that's how the bullet got into the wall. but then, where did they get that wall from? it can't be from the future, like they say in the movie, it must be a parallel universe.
there's a ton of things in fictional movies that dont make sense including character decisions etc. movies like this just do things even further into fiction until they are obviously not making sense. I can live with that. I just assume, in THAT universe (the movie's world presented to me) that it just works.
lets just go with quantum phsyics, the parts we don't really understand or can explain. The materials and matter that are missing... the casing shell and parts of the rock that were blasted away do EXIST in another time/dimension and the moment those actions are brought into play, that matter transports at a subatomic quantum space level back over to this reality, reassembles and is there again where it should be, from backwards time.
that's just no good screenwriting. reminds me of the nexus point rubbish in terminator genisys. :/
there are questionable parts in nolan's previous movies as well, but this time he really went out on a limb, or just doesn't care about believability any more.
see, I can't follow you here because all science fiction should do fictional science.... make things up that don't and often can't exist. we just have to go along with light sabres working, and superman can fly and such for it to be fun.
If everything has to be perfectly explainable, or realistic, we only have documentaries.
ALL time travel movies are rubbish. since time travel is fake. OR we can just pretend and have some fun with it. :)
