“That sort of thing is to be expected in a movie about time travel. But, in addition to being about time travel, Tenet is also about a charismatic secret agent saving the world and a beautiful woman from a Russian-accented megalomaniac with a superweapon, with all of the fights, chases, and dramatic confrontations endemic to the spy thriller genre.”

Two statements, same assertion:
1) “The sky is blue.”
2) “Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.”
Both statements include the same claim.
The first is a statement with readily observable properties and immediately available provability/disprovability. It allows for very specific discussion and debate, and a consensus on this point will allow further research into the factors behind it.
The second can still be discussed, but there’s so much context and reference that to argue it one must systematically accept or reject many assertions, and risk looking ignorant at each one.
The argument, in this case, is not strengthened by logic, but by volume.
