Your first fault is expecting that this anime is supposed to be like Higurashi or a bloody let's kill'em all hammering slasher fest when it isn't what it turned out to be after all, is that right? I think you are expecting this to be a killing spree kind of anime since you've mentioned Higurashi. Why should it follow your expectation when it can become something?

Second, Diomedea isn't a studio that is obligated toward fulfilling your own personal taste or expectation. Heck I doubt they even realized you are here right now mocking this work of theirs. I guess there are still countless people that didn't watch Shirobako, which is a great series that will make you mellow out and appreciate every other anime out there including it's staffs and everyone involved in the making. Or if you can't appreciate any anime that struck down your errr, preference anyway, at least the complainers would be more mature in their final decision before arriving on a field overwhelmed with mockery.

If you still want to continued this excessive use of rage, go on to MAL, you going to have loads of friends. Sorry if this message was too long, was getting bored and kept refreshing pages here before I saw your comment, or death threat.
