Oh, but the power of American superhero comics is that you can just start reading them wherever. Sure, there is deeper lore, but you’re not required to know all that. There’s this bat-dude, see? He punches crooks and does awesome shit in the night. There’s also a bunch of wacky villains. See? Just go read it, you’ll pick up the rest of the details as you go along!
And I also love a lot of European comics because most often they have a pretty good balance between complex writing and manageable size. And publishers here tend to be more lenient toward artists making one-shot kind of comics, without any expectations that it’ll become the next endless blockbuster cash-cow property.
Still, I do like how most of the manga series are like “OK, here’s the beginning, here’s 20 or whatever volumes, here’s the end.”
