Siblings being siblings, with the younger sister being more violent than most are. The opening is made up of fading, weirdly paced scenes from the episodes, so the opening is skippable and short. It's music isn't really a redeeming factor either.
The art style fits the short, quick paced tone of the episodes, the characters are well done for such a show, and it's not painful to watch!
I watched this in the japanese dub, and the voice acting was great.
Overall, there isn't much to say about this show, it's just hilarious and easy to watch, especially during office breaks.
