A few weeks ago, on a sick day, I watched the whole first season (I got that nice box set). It is *not* for children, and isn’t really for fans of large scale combat sims (I don’t recall any offhand), but otherwise it has it all. The behind the scenes stuff is amusing, because the accents of the performers suddenly appear. :’)
Apparently, they didn't have enough budget to do big battles and didn't want to use computer images.
It's fascinating to see that society come to life. I understand they did quite a lot of research to try to get it right.
