"At its best, Cunningham's "exclusions" have an emotional intensity that seems almost overwhelming at times. As in much classical poetry, the disciplined restraint of the form seems to intensify its power to convey and evoke emotion. There is something almost fierce and wild, as of a barely tamable animal, in his verse, which the form seems to be struggling to keep at bay; and the very strength needed to control the wild emotion somehow manifests its power."--
