I watched Mob Psycho 100 long before I even watched any of JJK or any of the other popular shōmen fighting anime out there. I didn't need any reference to reach the conclusion you reached in this excellent review: a masterpiece. Very few animated works from the East have as much action and such good story and character development as Mob Psycho. ONE (the creator of the work) is definitely a genius at creating characters who are both powerful and complex to describe and understand. That, I think, is what makes them unique and incomparable.
I loved this anime from beginning to end, every story, every arc, every character, every battle has its reason, its development and its outcome. It has no clichés, no fan service, no dark humor or anything that draws attention to what it really has as essence. This anime definitely breaks with what is common to see in this industry about the invincible protagonist or the hero who saves the world and shows us something more human and emotional.
Excellent review.
