This series is basically just talking. Talking, talking talking and talking. I know the other Monogatari seasons contains a lot of talking and mystery, but this one is the worse yet. It really didn't quite feel like the typical monogatari seasons where Araragi is the Main character, and he walks around to explore the mystery that the viewers also are queries about.
Anyhow.. Ever since I started watching this Monogatari series, I noticed a high frequency sound when sound effects were played. So I guess either the sound wasn't checked through an equalizer, or the people making these sound effects didn't have the possibility to hear these high frequencies.
Overall I feel like this have been the most boring Monogatari series Yet. But you might like this kind of mystery.
