I honestly love this anime... Short action packed episodes with an animation style that really fits the mood of this anime. Sure it's low budget, the animation is stiff and there's only 6 episodes per season. But the storytelling and the excecution of the production team make it way worth it. I assume you already watched S1 so you know that: If you accept it and decide to appreciate it as is then you'll love it.If you at least keep an open mind you won't be dissapointed.

Now... If you watch it expecting Ore Dake Level Up Na Ken level animation, then you'd be wasting your time.

I believe it's one of the best horror anime out there. I can only assume people that rate it low are hung up on the lack of production budget instead of appreciating how well they did inspite of the lack of funds.
