Pandora's Box (2021)

Both dramas are pretty dark mystery-thrillers with sci-fi elements. In both dramas, people die in weird circumstances.

Simmilar theme, same vibe, not many episodes, great acting, not much censorship and weird scientific mackgroud and explanations.

both have a strange way of conveying the story. both about consciousness and how easily it can be influenced by others

Both dramas are set in Japan (even if Pandora's Box is a cdrama).

Both dramas are short and weird. With Pandora's Box, the weirdness comes from the sci-fi elements and the plot. With Yamaneko, the weirdness mostly comes from the characters.

Both dramas have a similar kind of surprise villain.

These dramas are very different in many ways, but I did think of Yamaneko a few times while I was watching Pandora's Box.
