The lack of sense in a film, as well as in any other art, unavoidably leads to the audience's rejection. It seems humans are all naturally atheists when they have knowledge. Atheism is not a religion. I have read the letter of a woman who wanted to teach every religion to her students, including atheism. Atheism is the only non-projective perception of our environment.
Some countries are mostly Catholic, some others are mostly Islamic, etc.
That depends on the history of each country. Atheism is not a religion. It includes the whole science. Of course, some religions are atheist because they conceive the world without any God. This kind of atheism is not better philosophically than theists religions.
