The problem is not a lack of creativity: two thousand years ago there were stories being made, poems written, plays acted - and today there are thousands more original ideas in the same mediums produced every single year.
What do exist are archetypal story structures - but there are always exceptions to the rule, which because of the entrenched pattern of narrative that the audience has come to expect ("cultivation theory"), anything that tries to differ from it is often seen as alien and has a huge problem of getting over that barrier.
There are thousands of scripts written with brilliant dialogue, moving stories, deep and introspective observation... the list goes on. What, however, is produced on the big screen is a culmination of the need for profit and the assurance that certain styles of film will get the said profits.
How you go about solving that is beyond me. There isn't any sort of lack of talented actors, writers or directors, but they'll never rise to the top due to the economic factors which control the entire industry - save for notable exceptions.
When you remember that even the most common, down to earth people used to go and watch Shakespeare's (and his contemporaries') plays, and more than that - enjoy them - then the situation seems somehow very sad.
And what I just contributed to the discussion I have no idea. But I felt like a rant.
