Remembered this thread and just got done updating my list above. Wow, time flies by, 2018 was my last update. And it's pretty obvious that Corona is at fault for not only that but also the decline in great anime (at least for me). Just look at the difference from 2019 to 2020, lol. Anime basically came to a halt in 2020 and only the most reliable franchises continued. 2021 has been better again, but we'll see how 2022 can fare. Anyway, feel free to post your own lists or update them if you already have. I find this thread useful to spend time reflecting on the true personal masterpieces and whether or not anime as a medium is getting better/worse.
