‘Comics readers can be really parochial’ would be the mean way of putting it, but the fact is, comics are such a complex set of subtle visual and verbal codes that it’s easy to get thrown off by quirks in each continent’s approach to the medium, the same way that manga rubs a lot of Western (as in hemisphere, not genre) readers the wrong way. And there’s a resistance to the “album” format which I think to Americans’ eyes looks too much like a children’s book. But look, getting anything that’s both new and good to an existing public is always an uphill battle.
