You're absolutely right. It's a lot more calm and less bitching than in Western reality shows, but there were indeed some insane bitches in a few seasons. But most of the time it's HARMONY .... without getting boring. :)

And you're right about the panel and for many shows, esp. variety shows I find it so annoying, but for Terrace House I find it quite refreshing.

I'm sure the show is not for everyone, but give it a try if you have some time. ^___^
