Nice, The Spirit of The Forest is like the coolest thing ever. Right when I saw your words "forest god" I was thinking, "man, this kid better be talkin bout Mononoke..." Good job Anyway it makes sense, super influential movie to me. Thanks for looking!
Well, besides anything that Ghibli puts out, there's Ghost In a Shell which is quite famous and Akira. To tell you the truth Akira disgusts me. It's very grotesque but it's highly rated. Maybe you're already familiar with those two movies.
