Kowabon is a horror short series and is animated on live-action footage called rotoscoping. Each episode has a different short story.
I've been surprisingly watching this series since season start because the episodes are quite short and it's cool to see the animation based on the live footage (also gets shown in the credits which is a nice bonus). However the series is just okay to me in general. Certain episodes aren't that scary and is somewhat predictable. Also it seems to be "experimental" for the animators working on this series. Other than that, I just wanted to point this anime out. Overall, a decent horror shorts series.
Conclusion: A decent horror shorts series.
