Avoid unnecessary destruction and vehement is a good message that is sufficient to itself, no need to make tons ... Mushishi avoids this pitfall.
If sometimes the explanations can be complicated and difficult to follow, the anime as a whole is apprehended easily in my opinion.
The choice not to reveal any arc is original and very well thought out as it serves as the dynamics of the anime.
Finally the conclusion mood: mix of music, graphics, chara-design scenario is so relaxing, so enjoyable that we would like it never stops.
But Mushishi knows neither beginning nor end, it is a continuity that is in your mind and that it is your responsibility to life!
