I personally can't understand what would cause so many people to give it such bad scores of 1's and 2's and the occasional 3.
This show is a roller coaster and you will be crying by the end. (Of both the first episode and then again at the end of the shows 13 episodes.)
If you enjoyed shows like: Your lie in April, and Pet girl of Sakurasou. Then this show is definitely a good watch.
