For context: I vaguely remember watching the anime online when I was in middle school in like 2008 or something. I recently saw a list that said, "10 manga that aged poorly" and Elfen Lied was listed. Figured I'd give it a read since it's short.
Overall, it was good, I would have a hard time recommending it to someone though.
A lot of the scenes were overtly sexual or violent. The art was also pretty bad for a serialized manga - which the author addressed at the end of volume 8 I think - and it's actually crazy how much his art improved over the course of the series. I think the story starts to be less shock value and more of a story as it goes.
Calling the storytelling a rollercoaster isn't enough - it's more like getting punched in the face over and over. Lots of trauma. The second something seems to be going well it reverses. Even the quips back and forth between characters are like that.
Bando's redemption has to be one of my favorite parts of the story. I think he wrapped up all the loose ends the best he could considering the number of characters.
I could probably write out what I liked about each character but nah I don't have time for that right now. I think the manga and anime would have been more popular if it wasn't so extreme because the world and characters are interesting, but I also think the staying power as to why it's still talked about is because it's so extreme. I'm not an otaku by any means, but I have read all of Berserk, and Elfen Lied is honestly a harder read.
I see myself visiting the manga again? Probably not. But it was a good read overall. I might check out some of his other stuff, such as Brynhildr in the Darkness - curious about any recommendations people have.
