I think that went on a bit further than the 90s, probably up to at least the late 00s. I remember watching Elfen Lied a few years after it came out when I was in middle school and thinking wow, this is high art, I’m so sophisticated and grown up for having watched this! lmao
Looking back on it now, all I can think about is just how embarrassing that show was. The only nice thing I can say about it was I guess the intro was pretty dope
