I do agree that the threads immediately got more cynical and bitter after the incident, but I think the major issue is people come to realize how long everything is gonna take. I don't want pages zooming by with plot, but just realizing how longs it's been and how long it will be kinda sucks. The only way I can see Zach pulling this pacing off is if the comic is movie-tier and the story itself only lasts about a week in comic time.
He had filler and joke pages in the past, but that was when we could fully enjoy it and were excited and clueless about the pacing. The plot threads certainly aren't helping. Day one was way shorter than whatever day we're on, which won't end because we keep getting introduced to new things; and because Zach likes jokes each new thing is gonna come with more jokes that make everything even longer. Think of it like a movie full of jokes, that isn't a comedy (Age of Ultron, for instance). Maybe at first you ignore or even enjoy it because it's just part of the movie, but as note and more pile on you realize it's gonna keep going and it isn't as fun. That's what filler pages are like now. Personally, I enjoy every page, and like most of the jokes, but when I realize the page is a second in what will be an hour, it hurts my spirit.
