What is your best supernatural anime?

Do films count? If so, I'd go for Makoto Shinkai's 2022 work, Suzume. Loved it so much that I broke down and bought the special edition box set even when I didn't really have the cash to spare. Not only is its plot a really enjoyable adventure that dives into the myths behind Japan's earthquakes but it also is probably the most visually appealing film I've ever seen.
