I thought Season 2 actually picked up, going to watch Season 3 soon, and Season 4 comes out this year, so there is surely a market for it's relaxed style.
Is that Mushishi? It makes me think of it, another not well know favorite of mine. However, it's one of those animes designed never to really have a finale, and while that makes sense in the theme of the series, I kind of want a epilogue saying how the rest of his life went / what half the crap he saw in his life meant. It always felt like there was some subdued plot, but the Manga other ended it.
