The Storyline Trangle

That is what I call it anyway, what is it really? Its the plot, where you start with the exposition(setting/starting point)to rising action-climax("good" v.s. "bad" in final conflict)-falling action-resolution (the end) .Now this drives me nuts! You see this everywhere in movies,which are the most obvious, main character is set-main character starts winning conflict-main character starts losing conflict-main character wins in the end.This isn't just movies, they are in books, and tv shows!

So I have two questions,1)Is our imagination not as unlimited as we think and this is the only way to carry a story out? or 2)Is there a way to create a story without these strict concepts?

Try to give some thought into this and be reasonable and give me your ideas as this as frustrated me for years!

This is what i mean
