It is a rare thing in anime that a series fully adapts a manga and actually stays true to the source material. The anime adaptation is usually just a publicity stunt or a "reward" for good ratings for a popular enough manga or light novel, it's often not taken too seriously. The Mob Psycho anime, however, goes above and beyond, fully adapting the source material and staying with the original story and art style.
The story of Mob, his scam artist "master" Reigen and the odd ensemble of characters is one for the ages. Funny, intense, sometimes sad but also heartwarming. The characters are diverse and fleshed out, with their own personalities, strengths and weaknesses, and most of them do get enough screen time to be worthy additions to the story. The fight scenes are action-packed, well animated and intense, without going overboard with the violence, blood or grit. The character driven, more introspective, feel-y parts are also very well made and effective without too much forced tears or incessant melodrama. Even the humor is smart, witty and funny without resorting to bad slapstick or low-brow fanservice.
I'm sure just like many others, I would love to see more Mob Psycho, but sadly, the manga is finished so this is all we're going to get. At least we got to have a truly satisfying conclusions to the story, unlike hundreds of other - otherwise really great - anime, that never got similar treatment. It's a bittersweet end, but at least one we have. There is some tiny hope for some small, original OVA shorts or specials/spinoffs, but I think Mob Psycho already got the five star treatment it deserved.
If you liked the previous seasons, you'll love this one, and you get to see the conclusion to a great story! Highly recommended!
