Blends of Fantasy and Sci-Fi
Anime
Some of these are questionable, like Suisei no Gargantia can be argued to be fully sci-fi, but there is a feel to it that makes me include it, along with organic and archaic elements that are woven together in a way that makes this appear more fantastical than your average sci-fi. Similarly, Gankutsuou is sci-fi with advanced technology, but it's futuristic imagery is conceptualized to cohere with the elegant 19th century setting of Dumas' novel. I'm also avoiding the inclusion of more than one entry per series, so if season 1 is on here, then season 2 likely fits just as much.
