Initially it looks good but after 2 episodes it is ruined! The creatures are never explained, but they float and are hungry.
If you get it in original dub, japanese, you feel like watching a drama, to much emotional, about stupid people doing a service to save a young woman giving birth to a baby. Forget the scifi context.
But... If you are watching in Brazilian dubbing, you have to hear that bad accent of Alexandre Moreno crying as dr. Boyd. Be careful, it is hateful.
This episode 7 could be cut off and nothing would be missing at the whole story.
Sometime animation get slow and tedious... Everybody is just chatting useless speech while trapped againg at some base, alone, as all others already have flied.
Then they get runing again to other place, just as before, very easy to find a truck or new ship.
Maybe the original japaneses mangá drawing is a bit more interesting...
