Mob Psycho 100 is one of my favourite animes of all time. The only anime I enjoyed more than this one is Fullmetal Alchemist: Brotherhood.
Yet, I have to say that the story and the characters are pretty mediocre. The only character I find pretty interesting is Reigen Arakata. He has skills in so many other domains, but why did he chose to activate in exorcism? I like Mob too, because he is pretty relatable in my opinion. The story is pretty good, not outstanding. I like the main characters of ONE`s works. They are socially awkward, yet indestructible, a combination that I absolutely adore.
The art of this anime is just too good. I really love the design of the characters and the surroundings. I also love the intro and the ending, which are just incredibly well done.
The intro is by far ONE of the greatest intros I have ever seen (haaa, i made a pun there, ha, ha... yeah, I know I am not funny). It compresses the whole anime in just 1:30 minutes, and the soundtrack is just amazing. Adaptations of ONE`s work are simply amazing and I look forward to more Mob Psycho 100 and One Punch Man in the future.
