A Visit from the Goon Squad and Literature

I recently read 'A Visit from the Goon Squad' and to be honest, did not see its appeal at all.

I can appreciate that its a meditation on how we experience the passage of time but, to be honest, I didn't quite understand the high acclaim the novel received. First off, noticing the fragmented nature of how we remember time isn't exactly the most novel observation. Second, and more importantly, I constantly feel like Egan is nodding at the reader by trying to show how edgy she is, in her prose and how she presents the story. Not that I am against experimenting with chapters that read like magazine entries or PowerPoint presentations, but I lost interest in the book because I felt like she was doing them for the sake of it. It didn't strike me that any of this impacted her point about how we perceive time (or to her other point, which I am guessing is about how shitty it is to turn 40 when you've been a selfish asshole your whole life). If she is just doing this to be post-modern, well that's more or less old news.

I was wondering what everyone else's opinion is on 'A Visit from the Goon Squad' in relation to its legacy in literature.
