I watched a few clips. All I'll have to say is this: There's a not-so-fine-line between having fun with rural folk and making fun of rural folk.
I'm proud of my obvious rural roots and I understand having fun in the outdoors and not taking yourself too seriously ("Duck Dynasty" comes to mind).
This show is less: "look at the fun these guys are having and laugh along" and more: "look how goofy these rednecks are and laugh at them."
Obviously I don't know the people involved in the show; they may be fine people. What I do know is that the story is often in the editing, not in the shooting. Also, producers have a way of creating situations they think will be "good TV" that in no way reflect reality.
