You know, I was very worried when Green Creed showed up that they would do a whole beat'm up too. But nah, they played it super straight and I think that is the more mature route, not to mention a little more interesting. It was a nice Arc to inner peace and contentment. On the note of multi-season arcs.
I think my only gripe of this season was not really enjoying the character Silly Samuel...but we are totally gonna see him again aren't we? They completed Mr. Frog's arc and carried off Silly Samuel as a prophet. We're totally gonna have some Silly Jonestown; don't eat the silly sausage.
