I see what you're saying, but I have two main issues with the show.
First, Kate needs a therapist; she acts atrociously on camera, and I shudder to think of her in private.
Second, so many kids who grew up on camera have become absolute trainwrecks as adolescents and adults. There are too many to list.
With respect, how do you arrive at that conclusion? Are you qualified to make that comment? And you are correct that many child stars really do end up badly. I don’t think this is quite the same—they are being themselves in their own home with their parents.
Also, I know you will agree that this family has every right to make their decisions for themselves. This is what this site is all about FREE REPUBLIC. So I think that Jon and Kate have the right to pursue this show if they wish.
Those of us who like them should watch—those of us who don’t should watch something else.
