One demands two things of a poem. Firstly, it must be a well-made verbal object that does honor to the language in which it is written. Secondly, it must say something significant about a reality common to us all, but perceived from a unique perspective. What the poet says has never been said before, but, once he has said it, his readers recognize its validity for themselves.
