With Mushishi, it just first states the concepts of Mushi to you in the first episode or so. Every episode is basically a different story and it's very, very enjoyable. Just watch the 1st few episodes of the 1st season so you get the general gist of it. You can skip to S2 right after those few episodes (but I recommend watching all of it because it's fantastic).
Yup. All of that epicness. There are so many references and they're integrated so well. Animation and art style was amazing.
This. Although, I wouldn't really call it info-dumping though.
I saw episode 1 of the first season. I started falling asleep...no joke. I wasn't even tired. IT was just so relaxing and mellow.
Gonna take a look see of the mahou seitoukai animes first
Captain Earth is getting very good feedback. It's made by bones which is why I think its good so far
