This episode is the weakest of the season. The detective gimmick is fun for a few minutes, but the mystery is forgettable and the episode doesn't advance the plot at all. It's just filler.Meganebu just doesn't seem to be able to pull it together though. I'm starting to agree. The show is coasting on its art style and quirky characters, but the novelty is wearing thin.I'm still going to finish the season, but my enthusiasm is definitely fading.
