Boy, this is one hell of an anime. It's also one of my favorites and I consider it one of the most wholesome series I've seen, it makes me smile just remembering it.
As you say, the action is good, but the emotional charge behind each episode enriches the series immensely. Watching Mob grow, accept himself and open up to others was a tremendous journey that I hope to repeat soon because it's a delight.
I totally agree with your comment, it manages to transmit those things and it is a beautiful feeling.
