You had me at CGDCT...if it sucks, I'll just watch Girls und Panzer and Laid-back Camp again.

CGDCT is not my genre and mahjong is not a game i understand, and the extremely predictable result was that this anime flopped for me hard. It doesn't seem like it's doing anything particularly special or interesting other than those reference-humor faces the girls make. For CGDCT-enjoyers it'll probably be a comfy and familiar ride, but without an affinity for the genre all I can give this premiere is a 1/5.
