@Yuriel Frieren is very good, but it's also not for everyone. It's a slow but well done story about Time Lost with loved one who have passed, which is something i don't know if i would have enjoyed as much if i was younger
Try watching a couple episodes, and you'll have a better idea whether it's something for you. The first 3-4 episodes released as once, so that might be a good place to start. The quality is pretty consistent through the whole show, so that's about what you would expect if you decide to watch further
