What does cookie-cut mean here? What is he trying to say?
I think you can either look for forms, you can do specific reading for them, or the forms can be demanded by what you want to say. And when the material in poetry seems under almost unbearable pressure you wonder whether the form hasn’t cookie-cut what the poet wanted to say. But you chose the couplet, didn’t you, and some of your freest passages are in couplets.
