People ask all the time in the Suggestions forum for horror anime. Might this one qualify? This whole episode was rather creepy.
Sometimes the soundtrack in this show is a bit overwrought, especially in the scene where Saki prepares to leave. Still I liked this episode more than most so far. The direction in the sequence where Saki and Satoru look for Shun leapt pretty quickly from one weird scene to another. I guess we're expected to fill in the blanks. That seems the modus operandi of
Shin Sekai Yori pretty much from the start.
I presume given the level of stress both girls were under a bonobo event took place soon after Maria's arrival. I'm glad they didn't make a big deal of it, though they do like those giant facial closeups, don't they?
