I used to watch this show and truthfully it was because I found Kate's bitchiness entertaining. After a while though it just became incredibly irritating. She just comes across as a very ugly woman to me. I did watch the season finale though and I felt so bad for Jon. He seriously looked like he's on the verge of a breakdown.
It's sad to watch a grown man be emasculated once a week for a TV audience. I also think having your children grow up in front of a national audience is wrong. When those kids are teenagers they probably aren't going to be thrilled knowing the whole world has watched them bathe and has heard all about every gross poo incident.
