Yup. The few times I've seen the show (my wife used to watch, until it became even too creepy for her), I've gotten a definite cult-like vibe from the family (particularly the women and girls in the family). The recent interviews have done nothing to dispel that feeling.
I hate to say it but people will look at them and say/think Christians and homeschooling families must be like them. I sure hope not but it will not surprise me in the least.
