I'm not going to lie, I was intrigued by the concept. At first I thought this series was a romcom or something, but when I realized it was about a brother and sister, I thought I was in for some cute, feel-good anime candy. That's not quite what I got.
Don't get me wrong, there's some likable stuff here. Both Atsuhi and Atsumi are likable characters who act their age, and I've got to give props to Atsuhi's voice actor for being able to perform so well. When the show really wants to try, it'll deliver just what you'd expect. Nothing spectacular, but something kind of cute and quirky if you're into this kind of thing.
But then there are the pedophile jokes. Literally every other episode has Atsuhi getting arrested because he's mistaken for a pedophile. You'd think that his parents would take the time to explain things better. You'd think that after the millionth time people would recognize him and leave him alone. Comedic misunderstandings don't work by their very nature since the joke is literally making a character you're supposed to like suffer for something they didn't do, and it's even worse when it's happening to a 10 year old boy. I remember one scene where he comes home and curls up in a corner crying because he's so upset. How do people find this funny? It was extremely unpleasant for me.
Fortunately as the show goes along they slowly start laying off that gag, but its presence is still extremely painful. Like a parasite feeding off of what could otherwise be a perfectly decent, cute little show.
If that doesn't bother you, by all means give it a watch. Otherwise I say skip it.
