I really see no appeal to this show, it's a struggle for me to watch when I'm forced to. I remember watching it a lot when I was a kid, but that's because back then there were three channels, we couldn't get TV3 and TV1 was pretty bad reception.
The show is repetitive and, personally, boring. When forced to watch it, I know what's going to happen because I can almost always say "This happened ten years ago," and it will have, except with different characters... well, sometimes it's the same characters.
Also, sadly, there are often untalented actors. But that can almost be excusable, as there is admittedly little public outlet for actors in New Zealand to hone their skills.
In all, I feel that the show is rather cheap. So I guess if you want to watch something with limited quality, and you didn't watch the show already a few years ago, you can give it a shot, but I wouldn't recommend it.
