TL;DR:
Mob psycho 100 may not be the best of the best, but this anime definitely gets you hyped and amped to see the next episode.
Plot: 6/10
I didn't see anything special in the plot. It was pretty generic, but it kept my attention somewhat, so it deserves a 6/10.
Art: 8/10
The action and battle scenes caught my eyes a lot, and the style was very peculiar and interesting. A lot of the characters looked very different and specific, and this out-of-the-box thinking really struck it with me.
Sound: 8/10
The anime managed to deliver both an Opening theme and Ending theme that I found wonderful, along with the great OST that accompanied the show throughout its scenes. I found myself singing along each time the show started.
Characters: 6/10
You have a pretty normal weak-but-op archetype main character, with a bunch of other common roles filled in by others. I didn't see myself getting attached to any of these characters, although I did get quite pumped for Mob's explosions.
Enjoyment: 8/10
Although Mob Psycho 100 is definitely not the best anime out there, it is captivating and fulfilling. I recommend watching it for its interesting style, great action, and intensity. It was a great watch.
