I like them from a story-telling point of view. They introduce internal and external conflict just by existing. Internal conflict coming from the reality of them being inbred and their feelings about it, or how they treat their siblings/cousins. And external conflict coming from that now an enormous secret has to be kept from literally everybody, and there are 10 new inbred avenues for that secret to get out. Each of the kids react to their heritage differently, and the ways it affects them mentally create different scenarios for that secret to get out. And then you have conflict coming from the fact that the Loud sisters struggle to get along at the best of times, but now they're all adults and are forced to share the same single thing that each of them wants. It's a good opportunity to see how each character reacts to the idea of polygamy, their regrets about how their sins are now dictating the path of their lives, and lamenting the opportunities and friends missed. Or seeing how they've coped morally with the situation. Maybe they've convinced themselves it's not wrong, or they've just accepted it.

Because each best friend you have is a chance for you to fuck up and say something that you really shouldn't have without thinking. And if you're a kid, that's even worse; they tend to be more impulsive than adults. I could see any one of them getting too comfortable with a friend and saying "dad" instead of "uncle Lincoln". That can't happen, or else the entire family is fucked. The consequences of this secret getting out is that all the adults will go to jail, all the kids will go into the foster system, and everyone will remember the Louds as an incestuous sex cult. I imagine that the Louds are pretty socially isolated to avoid just this. Perfectly cordial, multiple casual acquaintances that they can wave 'hi' to, but no real actual friends. And that's going to have an effect on everyone's mentality and growth, adult and child.

I just think it's neat.
