Finished watching Tenet for second time today and the concept of inversion I get and don't get. The concept of simultaneously moving forwards and backwards from another person's point of view it kind of takes you out of the story. The only way to go backwards in time is to use the turnstile inversion device, wear a special kind of breathing apparatus because and once you enter the past everything is inverted. You kind of still get the concept of palindrome as well because the actions that you performed you tend to repeat it again at the same time you try to change a small outcome here and there. What's interesting after watching it for a second time is that Andrei Sato knowing the events before hand has to be due to the bodyguard that works for him. Somehow Sator from the future gives the message to his bodyguard to tell his past self as to what is about to happen. In a way there is kind of that Grandfather's paradox scenario coming into play. When it comes to the painting Branagh's Sator must have gotten it from his future self who sent it through the turnstile.
My theory is that Sator the whole time was keeping a watchful eye on the Protagonist and his wife from the future where he would send his bodyguard to warn his past self as to what is going to happen. The double inversion storyline that takes place in the film from the Protagonist and Sator's point with car chase sequence looked really incredible. The concept of inversion works both ways where Sator sees the protagonist moving backwards instead of forwards because it's from his point of view. When it comes to the Protagonist he sees Sator moving backwards but from an audience point of view he is moving forward in time. Tenet just takes quantum physics to a whole new level. What's great is seeing objects inverted in the spacetime continuum and that's due to the invention of the "Turnstile". Even the storyline between the Protagonist and Neil played by Robert Pattinson is a Palindrome because both of them will again meet up.
Christopher Nolan really is the ultimate mastermind when comes to creating intricate storylines and he that again with Tenet. He creates a puzzle and you get that in Tenet. It's definitely feels convoluted and he has done it purposely because he loves to leave the story ambiguous. He wants the audience to way in and that has been his trademark in most of his films.
