Shinsekai yori, Zankyou no Terror Recommendations
In both series, you need to use your minds to understand the story. Both series are boring at first but suddenly gets interesting midway. And both series has awesome twists and storyline that will make you score both series an 8 or above rating
Both Shinsekai Yori (SY) and Zankyou no Terror (ZnT)'s plot include children rising against some wrongs imposed onto them by elders and the structure of their society. Where SSY is historical and supernatural, ZnT is modern and realistic; both present mystery and thriller as its genre. I strongly recommend these masterpieces, a viewer will surely uncover this parallel between the two and then feel ecstatic!
Similar genre of mystery. Both have a dark plot and ingenious twists. Although the setting and style of the stories are really different, their 'darkness' are on par with one another. I would recommend both to those who enjoy dark mystery stories or want to be surprised. They're also my favourite anime series.
