To me that doesn't really look like anything special in narrative storytelling, it's just panels done more artistically. I don't have the page on hand, but the 16-panel page from The Dark Knight Returns showing the Waynes' deaths (spoilers) seems to me just plain better at the 'narrative storytelling' you're purporting that Batwoman does, because that page was actually storytelling, whereas the page you posted was more like 'check out this cool action sequence in this cool spread'. There are probably better examples in Batwoman, but you chose poorly.
Yeah pretty much just chose this page because it's dope as fuck, slightly limited by what Google has too. But you're right, that bit in DKR is very good, or even look at something like watchmen with the layering of narratives, sometimes three or four deep in a single panel. But really I was going for an emphasis that shows western comics can also be incredibly dynamic and visually arresting as well.
The use of colour has also come in in amazing strides in the past decade, something that I think manga would hugely benefit from.
I think this is a very roundabout way of trying to call people who prefer manga 'weaboos'. The preference does not necessarily lie completely with artforms (which seems to be the focus of your post). The 'westerner who is primarily a manga reader' is not necessarily a person who is 'immersing himself in a fairly alien culture'. Consumption of entertainment material is not in turn an act of 'definition pop-culturally' through this 'alien culture'.
I wasn't trying to cause offense, hence not calling y'all weeaboos but yeah pretty much, you as a manga fan appear to be into different stuff than I as a western comics fan. Just one look through your posting history shows me that. You're all about Japanese culture. And that's totally fine. But I'm guessing that's not your native culture, and so the choice to get heavily into it is a conscious one that you go into knowing that it's different.
IMO it's the same with any other form of cultural identification. "I am X", where X is "metal head" or "MMA fan" or "classical music fan" etc. IMO, a primary identification spreads out into other interests and is usually fairly predictable along certain lines, myself included.
Which is all a long way of saying "of course manga fans don't like western comics". I'll put it this way - I'm in to weird rock music, right? Therefore I've consciously opted out of mainstream music and won't like it if I hear it. This decision was probably in part informed by my liking comics as a kid, an activity that as an 11 year old was purposefully exclusionary (I knew my peers didn't like/get it) and that also led to me being into other niche hobbies along similar lines.
I think the same would be for someone who's a Japan enthusiast, one thing leads to another and before you know it, Japanese stuff is your primary cultural occupation, to the point where other more traditional forms of media don't appeal as much.
) feels totally unique in the genre and his style and voice shine through. I mentioned earlier that Wonder Woman is incredibly creator driven: George Perez, Greg Rucka, Gail Simone, Brian Azzarello, and many others have all left their unique marks on the character and her lore.
in the end its all just personal opinions and what not anyway
