It was worthy of one episode of Doomsday Preppers, but I can't imagine it being worth an entire season. A couple of the girls are pretty good looking, but then when you realize they all came from that father, it ruins it for you.
Also, someone (National Geographic) must have helped them finish that place, because after 20(?) or more years of working on it he didn't even have the ground floor part of it finished, and now it has towers and shit. He might have been working on it by himself before and now that all his kids helped, they got it done faster, but the gimmick of the Doomsday Preppers episode was that he was giving his fortune to the one kid that he felt could best continue his work in the event he died. He wasn't planning on finishing it in his lifetime. I guess that all changed, and now he's got that stupid living trust timeshare bullshit.
I'll probably download an episode or two anyway, because I love watching these crazy fucks. I work with at least one.
