I enjoyed your thoughts, because I think if I were really taking the episode as a whole, I'd feel similarly. In a way, I think I'm handwaving because Show took so long to get to Sam's breakdown that I'm just like, FINALLY they are fixing this, but it's a little too late. Ditto with Castiel's return. (And what is with mumble!Meg? She barely moves her lips. Is her jaw wired shut or something? *g*)

IDK. I don't think you're being too harsh.
