4-5 years late to viewing this anime but just throw some randoms thoughts out here anyways after a finished viewing. Thought the story of SG was pretty neat but ultimately ruined by the animation as it took a while to overlook it to just enjoy the interesting premise of the story and somewhere by the end the previous themes of the series built before seem to become lost.
It seem like a show that would have benefited a lot from a few animation buffs seeing how stylish and sexual it was supposed to be at times. The ending was kind of surprising in that everything basically went to hell. Things that just seem to be forgotten or I didn't understand.
It was sad to see how Saiga ended up in the end but at least he seem happy though
