This anime was rather good, it really pulled you in the first few episodes, however at a point it loses some of its steam and is just not the series I was expecting it to be. Basically, the story starts off great as this dude with some mysterious illness is put into cold storage so that one day he can perhaps be revived when a cure is found. He is awakened, but not to a bunch of doctors saying "We did it!". No, instead he is awakened in a nightmare as the earth has been overrun with giant insect creatures, his only chance of survival a mysterious girl using some type of robot vehicle to fight off the many different creatures now seemingly intent on killing people. This part of the story is great, seems they have some plans on using the dude to stop the creatures, his illness being the key. A lot of people are now living in space and this is where the girl must get the boy so they can begin setting a plan of attack against the bugs in motion. It is a really good series up to the point you sort of find out what the people with this illness are needed for and you ask yourself "what"? I just never got what was so special about them, seems like they really had no special ability to me. The series once it reaches the go back to earth phase kind of loses its luster that it built up in the very exciting escorting kid back to the spaceship part of the show. I also never saw the last episode of this series so while I saw all the others I still feel incomplete when discussing this start with a bang series. Just needed work on the second half of the show.
