At first, I was kind of pissed at the ending. A bit cliché, with MM showing some optimism from his self-proclaimed pessimistic point of view on life. I kind of thought they should have had an additional episode, kind of seemed like they rushed into it ..... "oh, look at this photo, green ears, tax records, hey, let's go to this house". I wanted some sort of better description of all the crazy crap.
And then I thought about Samuel L. Jackson's description of why he said that bible verse in Pulp Fiction "I just thought it was some cold-blooded crap to say to a [redacted] before I popped a cap in his ass". And, like, then I'm thinking why explain crazy; what possible explanation would satisfy me as to why a guy would target women, children and torture, rape, mutilate them for personal pleasure. Because the explanation of the yellow king, the rough ridin' weird redneck wood things, all of it, is that he's mumped in the head.
