I love this particular one. It hasn't had time to get dubbed. But it is amazingly gentle and yet captivating.
The Japanese have no trouble dealing with real-life situations and starting conversations about difficult topics. This anime shows the difficulty of losing a parent, being "unwanted", and adjusting to a new and 'different' kind of family. It reassures children that their family, no matter what 'shape' it might have, is legitimate and important.
