"Over The Garden Wall" is my favorite fantasy animation. Mystical & whimsical, got a special mood.
Bookwise I like "Neverwhere", also mystical & whimsical. I guess that's my theme. And I recommend the first 3 books of "Lightbringer" series, but avoid the last two. Cool magic, charismatic characters.
Latest favorite is "The Dragon Prince" Netflix series. Wholesome fantasy where the characters are really likeable and the voice actors phenomenal. 1st time I dropped it because the 3d animation is kinda bad, and the intro set-up is so so, but 2nd time I binged it.
