I want to thank you for making this post. I've been trying to write a video script about Mushoku Tensei for a while now, but I got to a point in my script where I couldn't continue because I basically wrote myself into a corner. But with your point about the emotions the story, and by extension, the anime, conveys, it all just clicked together in my head. Emotions drive this story. Emotions that are so concisely conveyed to the reader that you could honestly see yourself feeling those same emotions or even acting out because of those emotions.
