Totally on the same page with you about overlooked gems! I'd throw "Tuca & Bertie" into the ring, it's visually stunning and funny, with some really thoughtful moments about friendship and life. Another one that I think deserves way more love is "The Owl House." It's got such a unique blend of humor and heart, plus the character arcs are just chef's kiss.
And if you're into something a bit more offbeat, check out "Undone." It's got this trippy, mind-bending animation style that plays with reality in a way that feels fresh. What kind of themes are you hoping to see in these underrated shows?
