Usually Spencer's long books are good because he's actually telling one story, so when he goes off track to write about seemingly random stuff you can have some confidence that it is in some way related, and it always is. With Spider-Man, he seems to have so many ideas coming in and characters he wants to write that instead of trying to work them all into the main Kindred story he is just going off on tangents (that at best have minor links like Kingpin and Kindred which barely affect the stories so there is no reason to care about their connection.) So we get these repetitive three-issue arcs that are good in a vaccuum but do nothing for the main story, instead serving these subplots that we have to wait a million years to get back to that feel like filler because the book has relied too much on one mystery that is probably going to disappoint because they waited so long on it and because the book is light on other interesting questions and mysteries. For this book to level up, this Sin-Eater story has to be good, and it likely will be, but also it needs to bring actual change to Peter's life that will actually bring something new to this book.
