Didn't we have this discussion like a week ago already???
Haven't read #4 yet but yeah I agree with most complaints people seem to have. The book is too wordy, there is too much going on, it is difficult to follow and you'd have to be a hardcore DC fan to understand all the subtle references and easter eggs throughout... For me, after the first arc I'm probably dropping the book.
This coming from a big Snyder fan too.
