Well, its a bit difficult with this one. Its not shitty or something like that, but its definitely unique. The anime is based on little horror stories.
Story: 9/10
The plot of them is enjoyable and really interesting.
Characters: 7/10
I think, because of the length of the episodes, they characters are not really memorable, but still fitting enough.
Visuals: 7/10
Tthe art style is the special thing about yami shibai. The characters doesnt have any speaking animations and furthermore have limited movement animations, but not in a bad way. It makes it special and in my opinion, it gives the show a special touch and it makes it a bit more creepier.
Music/Sound: 8/10
The sounds were pretty fitting.
Overall Score: 8/10
