First is common sense .If you are in a view to to read and compare to real world then it will fail.You will be nitpicking everything and you will disconnect with film.
if you are seeing scifi then human brain will automatically tune to certail level of liberty and if you are going to see real biography dramas then human mindset will work in another level and try to compare
So If you want to read filmmaking point of view disable sound and see the first scene and you will know the brilliance of the film.Example is There will be blood and in first 15 mins there will be no dialogue but you will still able to follow whats happening because by brilliant acting,body language of charecter interactions and the theme
