My favourite underrated cartoon is Eek! the Cat, it's this great mix of cynical and wholesome - you've got this adorable, lovely character thrown into a harsh, tough-as-nails world, which is a common trope, but Eek! does it different by having positivity always come out on top despite the hardships. It's a shame that since buying the Fox Kids lineup (which yes, happened before the entire Fox buyout) Disney have abandoned this show apart from a few reruns on international Jetix stations in the early 2010s.
