Yeah I guess so. I just can't help feel like most anime is mediocre when I always see the anime community overhype the most mediocre looking shit. Black Clover, Demon Slayer, Goblin Slayer. Meanwhile Vinland Saga barley got any attention.
As you said it's probably just me being biased and cherry picking the good anime from the 80/90's. The truth is most anime released in these times are probably mediocre as well.
