I’ve posted those fe6 screenshots before and for an fe6 post from a blog with 1200 (roughly) followers it got a lot of notes. Please let this version be the one that gets more notes.
I like "The Fairly OddParents" and "Danny Phantom" for their potential for angst. In the former, you have Timmy's miserable life, Vicky's potentially traumatic childhood and Timmy's despair at the fact that Cosmo and Wanda must leave him eventually. In the latter, you have Danny risking his life, being horribly injured and fearing what his parents might do to him if they knew what he really was. Just out of interest, where's the potential for angst in "Bunsen is a Beast"?
