What is the drama of Nolan's new work Tenet?

I found many serious injuries after reading it for the first time. From a physical point of view, because time is reversible in some cases, and the premise of inverse time flow is entropy reduction, then an object in inverse time flow should obviously be entropy reduction. With all due respect, Nolan doesn't understand entropy reduction at all.

The car doesn't have to be driven backwards. The ground drives the wheels to rotate, and the wheels drive the engine to rotate. At the same time, automobile exhaust is inhaled and then turned into gasoline and flows back to the fuel tank. At the same time, oxygen is discharged from the air inlet. People either don't need to breathe or they don't need to inhale carbon dioxide. And it is necessary to inhale the discharged and excreted objects into the body, synthesize organic matter with carbon dioxide and exhale oxygen at the same time. Either way, you don't need to wear a breathing mask. Reverse bullet? How can there be a gunpowder kinetic energy weapon with entropy reduction? On the premise of entropy reduction, you can only convert kinetic energy and thermal energy into chemical energy of gunpowder, so how to use gunpowder kinetic energy weapons?

Let's talk about the problem of causality inversion first. For retrograde objects, the consequences are invalid at first. Then there is no such thing as "if you want to get it, you must imagine throwing it out first", because "thinking" is a cause, and getting it or throwing it away is a result. If ABC is sequential, then the reverse order should be CBA. But Nolan is talking about ACB. So people with strong mirroring ability don't understand, because not everything is the other way around! As a creature with positive time, human beings simply can't understand what it feels like to reverse time. If it must be set to enter the state of time reversal, then it is obvious that people can no longer think and can only passively accept it. The retrograde object and the advancing world must be independent of each other. Once the two intersect, it will inevitably lead to annihilation.

In fact, this setting of creed will lead to logic explosion, and the whole logic will collapse completely, without even a cycle. It seems that there are all kinds of "I know what will happen in the future but I just don't say it", "It's all over, but I don't know why, I just want to go back to friendship and play a wave", and various patches have created a seemingly complete and closed plot. But in fact, this setting itself has been eavesdropped to the point of irreparable. The problem is that reverse objects, people and positive objects and people can actually appear in the same world and interact physically, which is quite terrible, because the law of causality is not as simple as reverse here, but mixed and intertwined with each other, and the consequences are unimaginable.
