Supernatural meets everyday life. A bit philosophic, a bit sad, but also definitely very feel-good drama\movie about trying to understand things that are different from what we know about the world and thus scary to most people.
Both are about spirits and excorsim. Both are based on famous manga. Both are very similar............................ .
The supernatural theme of the story. Mushishi is much more passive than Gegege no kitaro. The actors: one is younger than the other. Might seem like one is the past and one is the future.
