As I haven't watched the anime or read the manga, Ajin live action was my first experiance with the story. The plot introduces the Ajin universe quite well and it explains it decently. However, the movie did what most of the live action movies based on manga-anime do: try to fit in too many elements in a few hours length movie and, in the end, the story feels flat. There wasn't time for the characters to develop or be presented in depth. Their motives were unclear at some points. However, the performances were really good and the action scenes entertaining. So, 6.5 out of 10.
