The bad ultimately outweighs the good for this anime, hence the score, however, it does have some highlights and, I will be checking out the second season. I don't see me ever rewatching the first season though. It seems like it just wouldn't be very enjoyable and a slog to get through. There were really only a handful of episodes and scenes I really enjoyed. The other stuff annoyed me and was hard to sit through.
The first episode is strange and fast paced, not terrible but, a bit of a disappointment. The season really didn't brighten up until Aira got more involved, but that was also short lived. She quickly became overshadowed by the stupid antics of Momo and Okarun again. Then Jiji shows up but, there's nothing really interesting about him until the last episode.
The animation is really not all that stellar to me. I really don't like this style of fluid motion they got going on, it looks shoddy to me. Other people do seem to love it though. I really like some of the creepy stills they do, but, other than looking pretty cool, they don't add much else to the story.
I think the anime struggles with keeping itself on track. I haven't read the source material so, perhaps the manga is just as bad but, it seems like the story struggles with balancing out a comedic and serious tone. I guess that wouldn't bother me if the comedy actually landed for me, but I can't get over Momo's annoying masculine voice. It's grating for me. Okarun's voice isn't the greatest either but, I've sort of gotten used to it. When Momo isn't being a spaz, her voice is fine, but when she gets excited, I get no enjoyment from her shenanigans. It's a very personal thing though so, some people may really enjoy it.
All in all, I personally didn't find anything to write home about. I don't think the series is without potential but, the first season was not very enjoyable for me. It's quirky though so, I guess to each their own. I wouldn't recommend it to anybody though since I personally didn't enjoy it.
