This is an odd episode and not one of my favorites. The Douglass family moves to California and tries to be friendly, but for some reason everybody hates their guts. This angers the kids who vow to never be friendly to anybody in California. I moved to California and it was never that bad. Sure, I had some bad experiences with psychos and murderers trying to kill me, but you just chalk it up to experience and move on. I don't hate California at all. I don't live there anymore, but I don't hate it.
All this is meant to create drama, but it's a weak idea in my opinion, much too cliche to be interesting. The best part of the episode is Katie, the "California girl". She's hot as a firecracker. Hot, hot, hot. So that's one good reason to watch it.
