I think they messed up the whole Leviathan thing. When they said they were hungry and threatened to eat everything I was expecting to see them eat everyone, humans, angels, demons, supernatural creatures, and the Winchesters trying to fight them but not knowing how to kill them.

Instead we go a group of creatures that, while visually interesting, only have importance in about a 3rd of the season's episodes.
