>>98177493A combination of a bunch of factors, the ones you named being among them.
First off, despite people's complaints otherwise, Bendis' name is a draw, so there were plenty of people buying the book only because Bendis was on it. Without him there, they dropped the book. Then you have the fact that Bendis did indeed poison the well. I know plenty of people that I know would love the book but refuse to even TRY Duggan's run (seriously, I've offered to let them borrow my floppies or send them links to pirated issues, and they just get indignant about the whole "if it's not DnA, then it's shit." Ironically, I was the one that convinced most of them to read the DnA run in the first place. Oh well.) So the Bendisfags are gone, and the DnAfags refuse to even give it a shot. Doesn't leave too many people.
From there, Bendis' run, for as shit writing as it had, had 10/10 art for most of it. Kuder is solid, but he's no Schiti. People that bought the book for the art and weren't onboard for Kuder probably dropped the book.
THEN you have the fact that Marvel in general is at its weakest point in years sales-wise. There are plenty of people that stopped buying Marvel entirely. I know some such people that didn't even know Rich was back until I told them.
So this means that the book lost:
>Bendisfags>didn't regain the DnAfags burned by Bendis>artfags>all the people that stopped buying Marvel books entirelyWhich only leaves, what, people that started reading the book because of the movie but don't particularly care about the name attached? Any hype for the franchise that the first movie created is longsince gone and the second movie really didn't manage to rekindle that hype near as I can tell.
Basically, any new readers came on during Bendis and didn't stick around, and what few old readers there were (remember, DnA's run wasn't exactly high selling either) were driven off by Bendis.
