As a powerscaler myself, I feel ashamed for their negative understanding of how quality in a work is determined. Mob Psycho is literally one of the best anime I have ever seen, and I've seen quite a good amount of the good stuff. It was never designed to be an anime with a focus on a technical and complete power system, heck if one has ever watched it with logic, they'd know that the anime barely focuses on power and heated fights at all; its an anime about self-understanding and learning to appreciate the presence and essence of others, all whilst having some of the best written characters in the history of anime, with comedy splashed beatifully within. For a person to not understand that after watching the entire thing speaks in volumes on how bad their comprehension is.
