It is a good anime, but
[Last Episode Spoliers]
The ending sucked. I thought it was really lame that Clare didn't kill Priscilla, since that's precisely what did in Teresa. Sure it goes with the whole retaining Clare's humanity thing, but really, if the whole point of the anime is to kill Priscilla, I want to see her dead. Sure she was kind of insane, didn't know she was a Yoma and whatnot, but that's no reason to have sympathy for her. Besides that the ending was just really inconclusive. Priscilla's still alive, Easly's still alive, the two other Dwellers are still alive, and there's just tons of unanswered questions regarding the organization and the people within it. But I guess that's what happens when a manga is adapted to an anime.
