When i first saw the Rating for this anime i was hesitant to watch it but after seeing it i was glad i did, first off the story of this series is very interesting. It sort of reminds me of Blue Gender crossed with Ergo Proxy, not quite the same but similar in the whole end of the world aspects and robots. This story left me with a heartwarming feeling that I don't get from most shows. There are some things it could have improved on, first off is the duration its a little short at being about 12 mins per episode not including credits,although it is a little short they dont seem to rush the story, However i do feel they could have gone a bit more in depth. It was made in the late 90's so the art and sound is a little outdated but that cant be helped I would definitely recommend watching this series it's very sweet and some parts leave you with watery eyes, this could have been a masterpiece if it only improved on a few small things but its definitely worth watching.
