I think the problem is, yes, partially with the fans, but more to do with the publishers not giving the comics a long enough period to attract a fanbase.
How long a period do they need? One year? Three years? A decade?
Blue Beetle was given three years and still failed to get readers. Manhunter was given three years and a relaunch. Captain Britain and MI-13 got a year and a launch that tied directly into a major company crossover event. The Order spawned directly from Civil War, had a hot artist, and lasted one year. New Exiles only got six months, but it sank like a goddamn rock. Spider-Girl got two different relaunches, three letter-writing campaigns, and two separate stays of execution from the editor-in-chief and still didn't survive. Everyone from fans to critics to pros said these books were good, and it did not translate into the sales needed to survive.
You cannot blame publishers for wise business decisions. Good original books do not last in the comics market unless they are tying into decades-old franchises, and that is one hundred percent on us. Comic fans vocally ask for new, innovative, ground-breaking work, then ignore it when it shows up in favor of buying Spider-Man again.
...at the moment, Marvel and DC are pretty much pandering to the long-time fans whose devotion to comics goes back to the Silver Age.
DC is, sure, with their continuity porn. It's just like the Silver Age except people are getting decapitated on panel.
Marvel couldn't be pandering less to the continuity crowd if it was personally dishing out cockslaps at conventions. Quesada and Bendis give no fuck for continuity and change it any time they feel like it.
People aren't pissed at Marvel because they're too mired in the past; they're pissed at Marvel because every single comic's status quo is in a constant state of flux, even when it involves people going OOC to do it. There isn't a single Marvel franchise where the 616 status quo hasn't dramatically changed at least twice in the last five years, with the possible exception of Fantastic Four. The fans have whiplash.
