Lol the idea that filmmakers inherently 'bring the truth to the world' is some absolute on-brand ideology. Sure buddy, Birth of a Nation brought 'truth to the world'.

Anybody with even an iota of communications knowledge (and even that is usually suspect in it's theoretical content) knows that, if the truth exists in the world, at best a film can mediate that truth (hence why it is call media), it cannot 'bring the truth' anywhere.
