I'm finding the Marvel U reaaaaaaly hard to get interested in at the moment. I'm reading mostly 'fringe' books like Villains for Hire, Punisher and so on. Also, a lot of their titles I dropped due to the $3.9US cover price (which is considerably more here in Australia), although some of those, such as Defenders, I've been getting digitally.
I have to say though that a big reason for my anti-Marveling at the moment is due to Bendis. Yes, his early Ultimate Spider-Man and New Avengers stuff was good, but I'm just tired of the way he writes. Seeing his name on a book now is a turn off straight away. I hate how he writes every character the same. Jessica Drew does NOT talk like Peter Parker. They both happen to have Spider aliases, that doesn't mean they are the same person. I'd love to read some Avengers, but Bendis and the price is keeping me away. I even dropped Amazing Spidey - my favourite Marvel book at the time - due to the ridiculous cost/ page count combination (although I'll be getting it in trade).
It sucks, but Marvel hasn't really isn't doing it for me since Fear Itself. I really hope that after AvsX things make a turn for the better.
Check out this thread in the General Comics section: The [apparently decreasing] price of comics. (not sure if that link works in the iOS app, though)
I looked for a single all-inclusive complaint thread about Bendis but there doesn't appear to be one. There are a lot of gripes about him and his writing methods scattered all over this site. I wonder if it's worth creating one.
