Man, what the hell is an "Ecchi" tag doing on this anime?
This anime has all the components of a successful emotional anime. It deals with the themes of loss, family and survival in a mature way and can make you tear up at more than one point, while portraying daily life of the protagonist with a sense of realism and without the tropes found in many anime.
If there was no "but" following this anime might be considered a mini-Clannad by those who viewed it.
BUT
The writers inexplicably decide that a show about loss, family and perseverance is somehow the right time to add run-of-the-mill pantie shots and incest humor. It's as perplexing as it is infuriating.
Now don't get me wrong. I am a... purveyor... of many a pantie shot and clumsy-airhead-girl humor bit. I don't immediately cry "FANSERVICE" and dismiss an entertaining anime. But I still have no need to have a tear in my eye as we watch a three year old learn the cold facts about death, and then ten minutes later watch a 12 year old tsundere's older cousin complex.
