It’s the 2010s by sheer volume of quality shows. Steins Gate, HxH (2011), Madoka, Vinland Saga, Fate Zero, Demon Slayer, AoT, Made in Abyss, Tatami Galaxy, MHA, Tokyo Ghoul, Psycho Pass, etc. During Covid, the anime industry kind of slowed down and I don’t think it has fully recovered. I don’t watch that much anime anymore either, it’s mostly isekai shit now.
