Best example of this: "Dean Winchester is basically the ultimate guy who can't catch a break, for years -- he gets kicked around by life, and stomped on by every monster in the world, while trying to save his brother from his inevitable cruel fate. Until at last, Dean gets a best friend, who's an angel. Castiel can basically heal any wounds, travel through time, teleport, and deal with just about any problem using his angel magic. So once Dean and Cas actually become friends and Cas starts coming whenever Dean calls him, does this solve any of Dean's problems? It does not. Mostly because Cas is kind of a weirdo."
