The section I found most intriguing was when McCloud discussed comic transitions and how they are used in chapter three entitled "Blood in the Gutters". He first talked about the "gutters" themselves and its power to imply events not shown to the audience by providing the them with closure. This naturally segue into panel transitions and forms.
The first transition mentioned was "Moment-to-Moment", it's when the panel focuses on the moment and it creates little closure. Next was "Action-to-Action", when the panels focuses on a particular action shown. Then there was "Subject-to-Subject", where the focus is within a scene or idea and requires higher degree of reader involvement and closure and without these factors the panels would not be as meaningful to the viewer. After that is "Scene-to-Scene", it is a transition that shows time and distance. In those panel deductive reasoning is needed to understand it.
He compared western comics to each other and noticed similarities with the about of the types of transitions used and the fondness of the action-to-action transitions. Even something as wildly different as Tin Tin and Fantastic Four that differs in both aesthetics and writing share similarities with transition trends. It gets even more interesting when McCloud compare comics with manga. The trend remains mostly similar except with the addition with aspect-to aspect transition. It shows the very eastern style of mangas and it ties with feudal era Japanese artworks such as Hokusai's The Great Wave off Kanagawa, Maple Viewing at Takao by Kanō Hideyori, and 13th Station: Hara by Utagawa Hiroshige. That style of showing pieces of the surrounding gives it an atmospheric and cinematic feel and slows down the pace.
I find it interesting that despite media such as mangas that is meant to be consumed quickly it still takes it's time with these aspect-to-aspect and moment-to-moment panels. It takes advantage of the fact that tankōbons have hundreds of pages in each volume in comparison to western comics having around 10-30 pages for each issue.
