I never believe it was anything but what TLC wanted us to see. I understand what you are saying now. But those are just words. None of the shows are actual. It's all for money. As long as they are considered reality shows, many will think that's what they are. I always assumed that what Kate meant is, they didn't cut out the 'bad' parts (although apparently they did some of them LOL). Didn't try to make her look nice, didn't try to make the kids perfect (no hitting!).
I haven't been to a speech Amy has given, so I have no idea what she says about the show. They are seldom on anything with interviews, although I bet they will be soon, if they keep portraying them like they are.
