If you were to tell me that there was this great new anime series called "There's no way my little sister can be this cute," I'd look at you strangely and slowly back away. But, in a fit of boredom, I watched it, and it was good. Well, better than I thought it would be.
This is mainly because the main male lead is such a good character. Kyousuke just wants a normal and dull life (like Rincewind form Discworld), and stays in the background. In contrast, his little sister, Kirino, is an overachiever, and thus is the favoured child. She's also a tsundere of the worst sort, so I don't like her that much. The two are distant and have a badly broken if existent relationship.
This is all turned on its head when Kyousuke finds out that Kirino is actually a closet otaku obsessed with, ironically enough, little sister eroge.
Repeat to yourself, it's just an anime, you should really just relax.
But not only does Kyousuke agree to keep Kirino's habit a secret, he also agrees to help Kirino find people like her. He would win just because of that little fact, but it turns out that the plot would do anything to cause trouble, and he usually sacrifices himself for Kirino, who both bosses him about and beats him up along the way.
Yeah, I really don't like Kirino.
Which is a shame, because she is, literally, the only character I detest. I like Saori and Kuroneko, the two other otaku; I like Manami and her family, who are somehow able to be simultaneously both kind and hilarious; I like Kyousuke's mum, who sticks up for him when he has to go up against his dad; I even don't mind Kyousuke's dad and Ayase, who provide an interesting antagonism to the otaku plot (and I understand them drawing the line at the NSFW material, I mean seriously Kirino, WTF?). But Kirino's there to be 'adorably' tsundere, and the ungrateful whelp doesn't deserve help. (Okay, she says thanks once. Once.)
Besides, the thoroughly unlikeable female lead, this is a decent anime. Check it out.
Oh, and KyousukexManami forever.
