I have loved this show for so long. Having said that......
For me, it seems as though this season, Kate is "Hollywood Kate" instead of "real Kate". J&K+8 is no longer about everyday life with 8 kids--a big family and their day to day challenges of handling 8 kids in a loving home.
It's now about places they travel and all the things they get for free and I feel, too often, "suttle" ads for sponsors.
Kate the movie star (now) vs Kate the regular mom (before). Their original life, which is the one I tuned in to watch, doesn't exist and I fear for those kids what becoming famous may do to their family.
I hope Jon and Kate have some time off to re-connect , if possible, and perhaps seek some counseling. I hope they can both find a way to be happy.
