Frieren is a slow burn for sure. I understand it is not for everyone, and that's okay.
To me, it's the best anime I've watched in a while. The slower pace lets scenes breath and the melancholic undertones resonate with me right now. Isekai has really flooded the market right now and to me this is such a breath of fresh air.
I think with the anime you listed there is definitely an anime in the current or recent seasons that will speak to you. I recommend Mashle. To me it's One Punch at Hogwarts.
In Sync for Reddit we had the ability to view previously upvoted posts. I don't know if Lemmy supports that, but that was a feature I used often to go back to something. Thanks
