I think they've forgotten that Captain Hero has super powers.
I know his character has changed, and he's become increasingly more... unknown.... for better or worse. But I still think his super powers should come into play sometime. Otherwise he's just another crazy character.
For instance, when they were all trapped in the carriage underwater. I just kept thinking, why the hell doesn't CH just bust through that s***? I think they even showed him beating on the side of it with the rest of the cast. Instead they just came up with the completely random idea of making Ling-Ling a float.
I mean, I know this show isn't big on plot points, but comon. Use the characters you've got to the fullest. I like CH's weird-ass ways, but I also don't like that they've pretty much used that as an excuse to forget that he's supposed to be a parody of super heroes.
