It's better than Shin Chan and PingPong as well as most 'reality show' garbage on TV. You could find better shows, but this one at least won't kill you. Unless you're one of those anal otakus that rates anime with the grandeur of biblical scrolls that's cornerstone of actual societies.
That being said, I'd rather watch reruns of other shows than to rewatch it. But I'd watch it if I hadn't seen it.
