I think I disagree. J2 AUs are a strange, strange, beast. But I love them dearly. As a genre, they taking what we know of these two men, distilling them into characters, and then throwing obstacles in the path of their Epic Love Story and then having them overcome the obstacles. Of course Jared IN SPACE probably won't eat gummy worms. But if the character isn't recognizable it's like ... a softshoe tapdance. Half the fun's gone.

I've read a couple of fics where Jensen's all uke, and they're hilarious. Umm, guys? He only looks small when he's standing next to Jared. Seriously.
