What makes a poem good?

I have one disagreement with Shannon. There is a difference between whether a poem is good, which to me means well conceived and written, and whether it appeals to us. For instance, ee cummings is clever; his poems are good. However I personally don't care for them.

This also has to be distinguished from whether the poet writes in a style I like. WC Williams is definitely good (though in some cases I believe excessively fawned over), even though his style is far different from my own.

Assessing a poem is very difficult when the piece is in a style we don't care for and on a subject that disinterests us (or takes a position contrary to our own opinion). That requires great objectivity
