I would say that this is true of comics which are of the "superhero" variety, but not so much of others. Which is why as a comics reader in my teens I avoided those comics, even at a time when they were attempting to subvert their formulaic tendencies. Unfortunately, Hollywood has been terribly formulaic, and I suspect that this is why comics movies have been catching on. For better or worse, they deal with familiar archetypes.
Personally, I think they would be better off making movies of comics which defied formula, such as Zap! or Tales of the Unexpected.
