Of Course It Is...! When done with the best of your abilities and directed at an idea that you want to portray (whether the idea is made clear or hidden with in your own personal meaning). A Poem can say things with great imagination and with great attention-getting abilities...i.e. Art! In its purest sense.
Perhaps Poetry is even better then most media forms that are out there today. It only depends on how interested the person is in the Poetry that they read. Art is where you find it. Artist seek to express their ideas...in the form of their own choosing. Some use plaster of paris and a kiln, some carve wood and stone, some use colors on canvas, and some use words! Hooray...for the Artist who expresses their ideas in any media form!
