Yes, although I'd be hard-pressed to tell you exactly what, since I read it a while ago and I don't have a copy I can look at to remind myself - I have a strong memory of the realization/impression itself, but not of precisely what triggered it.

I think one of the things was the usage of third-party narrator voice? - most graphic novels I've seen use it pretty sparingly, if at all; most works I've read that are liberal with its application are comic books.

There were other things, too, I think, but they flee memory.
