I mean, Black Lagoon is easy to explain hot chicks, guns, feeling like somethin Tarantino or Rodriguez would make, over the top action.
It's an awesome show with obvious appeal, but there's a lot of cool shows from around that time that are forgotten, why does Black Lagoon buck the trend?
Part of this could be simply distribution, I saw the boxset of Black Lagoon at Target, Gunsmith Cats got a nice blu ray in 2018, if this stuff is more easily available that can explain why it gets a second wind as opposed to shows long out of print.
But is Black Lagoon popular because you can buy it at Target or is it at Target because it's popular online? Same thing with the Gunsmith Cats BD, did it introduce it to a new generation or did it get a release because of it's following?
And then there's Azumanga which iirc has been out of print since 2016 and iirc has not been released in the US in HD at all, I'm also pretty sure Lain has not seen an official release in forever (though I could be wrong), these seem like shows that stuck around because of memes and fans downloading them, I'm also pretty sure Golden Boy has not has an official release in forever.
Another odd thing about Black Lagoon is it seems like it's more successful now than when it was new, why the delayed response? Maybe it could have saved Geneon, but it took another decade and change to actually find a following.
Don't get me wrong, Black Lagoon is one of my favorites and I'm glad one of my favorites from around that time is well remembered, it's just too bad it hasn't happened with more shows.
Maybe its because they have a neat retro visual appeal without the cringe of being too ""anime"".
Like I said they all have a kind of meme "stickiness" to them, instantly recognizable characters, or other aspects that just lend themselves to the modern social media age.
Revy stands out among anime girls because of her crass, badass attitude and she's not even technically Japanese at all but Chinese, she has that "girlboss" energy thing going on that has obvious appeal to people today.
Lain is a depressed girl who spends all her time on a computer, a perfect "literally me" character.
Azumanga has always been heavily memeable.
But then you have something like Maria Holic, it's not out of print, it just recently had a BD release in NA, it's un-PC handling of LGBT themes and general bitchy sense of humor seems prime for modern meme culture, but yet, silence... (it was fairly popular at the time it was airing, but has been forgotten ever since)
Maria Holic's original manga fyi infamously triggered a lesbian yuri blogger to tears, it's a funny series that deserves to be rediscovered.
