Animation, art, sound. were pretty good but emotions shown by characters, story telling everything in the anime gave the feel of the real life.
It was like even if is was a real story it wouldn't be surprising.
Unlike Gankatsuou or Deathnote it doesn't have anything supernatural and unlike psyco pass there is no special gun or something. Its a story purly feasible to happen in real life.
This is why this anime is quite unique and different from all the others. Its a one of a kind anime.
This is definitely one of best anime ever made. I would like to watch more of anime like this one if there are more.
