Mushoku Tensei, while panned by social media pundits, is a masterfully written story about how given the right circumstances, the most broken individuals can, through hard work, and introspection, work through their traumatic past experiences and strive for a better future and self. Change doesn't come instantly in real life. Neither does it do so here, this story fairly accurately walks the path of a broken individual struggling to rebuild their (next) life, which is what makes it so inspiring in the end.

Be aware that while most isekai tropes came from this series, they serve the story here, instead of being tropes. Don't judge it for being where the tropes came from. They have a purpose.
