Mystified by the opinion that this 'is by no means an easy read' – I powered through it in a couple of days. The book's heft is misleading, rarely are there more than 6 panels a page. But Mazzucchelli uses those pages like an expert: style seamlessly folded into the storytelling. My favourite sections are two largely caption-less chapters near the end summing up the best and worst aspects of the protagonist's relationship with his wife. Mazzucchelli's interrogation of the idea of duality permeates the narrative, but ultimately it succeeds because the title character is so likable, before and after his transfiguration.
