This is my first time watching an anime with this sort of art style. To be honest, at the start it was weird but when you really get into the story and focus on whats going on, you don't really notice after a while. I must say, the art style makes the story better. if you pay attention to what the story is about and how the characters speak and react to things, you would realize how very realistic it is. Thats why i believe the art style was well made for this, gives the story a nice flow and heartwarming feel about it.
