I watched the most recent episode last night, and for me the "jump the shark" moment is Kayce's ridiculous storyline involving a lone wolf and his vision quest.
Seriously...this guy is the Livestock Commissioner of Montana, a state that, for all I know, conceivably has as many, if not more, cows as people, and this guy is going to sit out in the middle of nowhere for four days, completely neglecting his appointed duties as said Livestock Commissioner of Montana, while getting stoned out of his mind and not eat or drink for four days?
Man, must be nice working for the State of Montana.
I've been watching this show since Episode 1 of Season 1, but the plotlines are increasingly absurd and nonsensical. I'll watch the season finale next Sunday, but I am firmly on the fence right now about tuning in for Season Five.
