The main reason for my low rating is that this series isn’t like the original Higurashi series. It totally lacks the horror/suspense element that was vital to the original anime. It appears to be strictly a bit of fan service and a painful continuation of a series that had already ended.
However, this series is good for a fan who wouldn’t mind seeing a light hearted version of Higurashi. The first and last arc is non-canonical. They often break the fourth wall and lightheartedly reveal major plot twists (such as miyo’s true nature) to character’s who are largely aloof to the new knowledge. The only episodes I recommend are 2-4 as they are the closest to being canonical. If you don’t mind seeing the girls in bathing suits, watch episode 1. If you want to see hilarious romantic parings, watch episode 5.
