While I certainly do not envy Kate, I really can't stand the "editing" defense. You can't EDIT someone into a control freak. The footage has to be there in the first place before it can be edited into anything else.
However, they would not be on TV if there wasn't something to watch, and watching a perfectly run household just isn't as entertaining. I think it's great that they don't spank, and that they strive to eat organic and homemade. I think most of us agree that she isn't the world's worst mother.
The biggest problem I have with her is that when her kids grow up, they aren't going to remember that she mopped the floors three times every day (unless the part of that that they remember is that they were relegated to another room three times a day), but they will remember the fun (non-forced) good times that they had together. Kate seems so focused on forcing memories, and not so much on the act of MAKING the memories. (The episode with the pumpkin carving comes to mind. She couldn't just enjoy it, she had to be all concerned about cleaning up before Jon was even done, and the kids were clearly having a good time.)
I'm not even going into how completely nasty she is to Jon. You can't blame the way she treats him on editing. She's had a chance to watch herself on TV, and acknowledge that that is an inappropriate way to treat her husband, and she continues to do so. Free Jon!
I DO think that there is a lot of producer involvement this season (between the blatant product placement of the worm-looking ride on toys and the Rose Petal cottage, and the trip to Chocolate World without Jon), which is annoying. I'd really like to watch a typical "day in the life", like they did last season with the episodes about grocery shopping and when the twins went off to school during the day. If I were her, I'd negotiate with the producers - they need to pay for an hour of therapy a week in exchange for trips to Chocolate World.
