I will be short and precise.
I will include NO spoilers.
This anime was very much like the light novels, but it was also lacking. The light novels had much more on the characters that the audience could see and the story was easier to understand. In the anime, an episode can jump from one stage in the protagonist's life, to another with inadequate representation. I believe that 25 episodes was not a sufficient amount time to fit in three years of the story. It just does not make sense to attempt to fit in four volumes of the light novels into 25 episodes, in which each episode lasts only 23 minutes. Entirely mediocre.
Does this mean the anime is bad? of course not. I say mediocre because it is neither good nor bad.
This is a very good presentation of the light novels, but it is not perfect. Think about it: if you were to fit in four award-winning novels into 25 episodes, less than 600 minutes, and only 9½ hours, would you do any better? The story in the anime only had the important parts, only a partial amount of themes the audience should have experienced, and little character development.
All in all, the series was in fact enjoyable. I have not been able to immerse my imagination into an anime series since the younger days of "Naruto" or "One Piece".
