This page is a list of all the animated series that I rated at least one heart, i.e., all the shows I love. I'll be listing them in order of most loved to least loved, but they're all top tier shows, IMO. (Please note I'm not 100% sure of the actual order these should be in. It's hard to remember/judge.)
