It seems I'm not alone in thinking Adam Lipkin's review of Iron Council was unnecessarily negative.
The Mumpsimus initiated a discussion of this and other reviews of Miéville, touching on how his writing might be improved as well as the strength of his media appeal. He is compared to Wolfe, his writing being unwieldy and needing an editor.
I'm reassured that others don't always feel plot is paramount
