Man, don't get me wrong, I'll still watch the show, but it really bugs me how they introduce these possible interactions, and just kind of let them die.
Allura's racism towards Keith? Mentioned and resolved in like two episodes. And then their connection is never mentioned again.
Pidge's quest for her brother had most of it's events and wrap up in one episode.
Lance's feelings of inadequacy, one episode, and they never touch on it again.
Man, we never even got to see how Pidge got her lion other than just jumping in a hole.
I know I'm nitpicking, but these little things add up. 52 episodes in, and there's no real feel for the characters personalities. >tl;dr why isn't Voltron written more like Avatar:The Last Airbender?
