Anime:

Rewatched Ga-Rei Zero with friends and it holds up; be careful to avoid episode 1 spoilers. Fun supernatural fantasy/horror action, with character relationships that develop and make sense so that one is drawn into caring about them.

Knights of Sidonia is only four episodes in (so may yet turn bad) but it's the most interesting sci-fi I've seen since Shin Sekai Yori; spaceships that feel realistic, and hints of the social/political consequences of life on a generation ship. Animation is CG with these over-smooth faces which may be a deal-breaker for some; together with the used future aesthetic the early parts reminded me a lot of early Ergo Proxy.
