Barakamon is a heart-warming; very cute and funny Anime.
After watching it I decided to review the Seiyuu's (Voice Actors) and I found out that actual children did the children characters in the Anime. I enjoyed how the children grew fond of the main character and especially in the comical parts where the kids would teach him new things. I also liked how it was set away from urban life and focused on a rural environment.
There isn't really an antagonist, just struggles for the protagonist in which the children help him see how to overcome the problems he faces. I highly recommend this Anime if you enjoy COMEDY.
