WHAT IF IT'S NOT TARANTINO?

27.08 I was in Angliter, friends. I watched the acclaimed movie "Once upon a Time in Hollywood". There is still an aftertaste and a lot of questions. And a dream with a fragment from the movie.
What is art, I ask myself? What and for what purpose was it created? What should I give to the world by being a part of this process? 
What should or can the director give, what message does he carry? And does it carry? And should I? And to whom, for whom is he making a movie?
Questions, questions, questions. I'm not a critic, as you know. I'm just a spectator and a thinking person. Not quite educated (not to be confused with the mind), but not at all biased, due to his lack of education.
