I LOVED this anime. It had a very unique storyline that kept me interested until the end. There was very few fillers, and the characters are realistic (being that they don't have out of proportion body parts, random personalities). It has romance, action, unexpected twists, I think it is definitely worth watching but the first episode explains everything so it might be a little boring for some people. And for those who love space, pretty images of the universe, you'll get a huge dose of it :)
