I agree, and believe that poetry has the ability to redefine creative writing in many ways. I’m also a script writer and that is flat out painful to produce because of its forced and strict guidelines. There’s no taking creative license with it and each script has a different format ie: feature film, tv series (reality vs scripted) it’s all scripted, but forced into specific constraints.
Poetry should be like a bird. They can fly straight as an arrow or circle and swoop. I’m all for structure in poetry if that’s what you’re into, but I think the exact opposite is just as poetic as the person who commits to a teardrop shape or an A-B-A-B rhyming pattern throughout.
Poetry in itself doesn’t require rules; it requires visualization, storytelling and emotion. (Not necessarily at the same time). Poetry exists in the world before it falls to paper in the form of words. People create the format; they write the poem, but “poetry” exists before you pick up the pen.
