Now here is something interesting about Tenet IMHO. It actually isn't a time travel movie technically. You will see what I mean with the following example:
Suppose we could arrange all the elementary particles in our universe in exactly the same state and position they were in at some time point on June 10, 1974 (we'll call this T0) along with the universe itself in its exact level of expansion at that point (our universe keeps expanding ever more rapidly into the void as time moves forward). Well if you could observe our universe in state T0 it would be no different than if you had time traveled back to that point in time in 1974. But you didn't - the elementary particles of the universe were re-arranged to be exactly the same as they were for that time point so you could not tell the difference. So it might as well be time travel in terms of what one experiences, but that is not what actually happens in this example.
Well the same thing is happening in Tenet. What got invented was a method that can put an object in reverse entropy in that movie. So the object returns to the state it was in at an earlier time, but no traveling back in time is done (the object's molecules just move back into the position they were in at an earlier time when exposed to the reverse entropy method that was invented in the future).
