I have been slowly making my way through Uchuu Kyoudai(Space Brothers) on crunchyroll. As a grown up who spent his whole childhood dreaming of going to space this series hits me hard. It is quite a good anime on it's own. The voice acting seems pretty good, the artwork is quite nice (besides the so-ugly-its-kinda-cute dog Apo), and the story line is nice and straight forward. There are no surprises really.
