*hides in the corner*
I have an elder sister who's lazy and forces chores on me and mom, but holy hell Umaru's indoor life is just terrifying with her extreme laziness, immaturity, and a double "perfect" life. Even her avid gaming life is incredibly scary when she's literally plucking out all the toys from the crane machines. As much as I want a little sister or a daughter, I'd be utterly frightened to be an onii-chan to and constantly pestered by someone like Umaru.
Aside from that, it makes frequent references to other games and manga/anime, and I'm surprised that it has Monster Hunter in its opening. Otherwise it's a relatively interesting series to see how Umaru's multiple personalities interact with others.
