It is hard to provide specific criticisms of a work one does not understand, and which makes no testable claims. If it is just one reviewer, then he may be missing the point, but if it is everyone, you have to give some thought to the possibility that it is you who is mistaken. In principle, someone could be both right and incomprehensible, but there's no way forward unless one can get some people to both understand and agree with you. Even then, you could end up with one faction thinking it is on to something profound, while another thinks they are mistaken, as is happening with Integrated Information Theory at the moment.
