You might like My Little Pony. It is with animals, but it is a lot about how relationships really work.
I am with you on superheroes. They do nice power fantasy, but lack actual tension, because main hero is unrealistically over the top strong. Consequently, the mechanics of "how the world works" are also all wrong.
+1 on My Little Pony. Equestria Girls is great - characters can be irrational and selfish and mean, and friends have serious arguments and fallings-out, but their commitment to their mutual friendships works out in the end
