If I had to guess at why people don't like poetry or think it's a bunch of words without no value is because it doesn't really talk to them. Poetry to some people doesn't communicate to them the way a tv show or a song does. It's not simple enough to be understood and it doesn't have the action that people seek. When a person talks about their emotions in a poem, their words are only felt by people who have been in their situation before or those who are open to the language of a poem. When people see poetry, they see this complex thing that they don't want to deal with because it's usually a thing they don't have to deal with.
