Black Butler is one of the most frustrating anime series of all time. During some scenes, it achieves a mysterious brilliance, molding steampunk with noirish elements. At other times, it feels so childish and fleeting. The series, newly arrived on Blu-ray and DVD from FUNimation, never overcomes this tightrope balancing act. Scenes of drama are coupled with silly pranks, leaving audience members scratching their head more times than not.
