Complete and total lack of direction, and nothing unique about these shows.
Usually the summer is a bit slow, but typically, there's at least a general build toward whatever SummerSlam is supposed to be at this point.
On top of that, every single one of those shows is the same. There's no variation in appearance, and their roster is limited, so you're seeing the same people just get shuffled around. I've said it before in one of these threads, but a large portion of their viewers are living a monotonous life right now, where every day feels the exact same. Why follow that up with watching a show where every episode feels the exact same?
