Hi,
i was looking for some based discussion about this anime and i thought perhaps this is the best place, if one can be had.
I personally found it refreshing as i gave up anime long ago but remembered this one as a good one, so watched it again lately.
Aside the graphics which i really liked, the way the story emphasizes all those aspects which are generally discarded in favor of action is a strong point. It kind of break a lot of cliché for what you can expect in an anime.
Most of the story also is pretty metaphorical, or expedient to talk about/show concepts.
The robots infected by the virus that made them think and instinctively start praying, the humans that living in a perfectly ordered society start becoming more and more like robots. It's quite a well thought out, ironical critique.
It's been a while since I last saw it, but I remember liking it a great deal at the time. The game show episode definitely stands out as one of the more unique oddities of the anime. I might give this one a rewatch fairly soon.
