Sasami-san@Ganbaranai doesn't have a very good score at myanimelist, but I'm currently at 8/12 episodes and it has rather impressed me at points.

It's from the same company (SHAFT) that produced Madoka Magica, and I think the element it shares with it is that both attempt to do a sort of redemption of the ludicrous, as Adam Cadre would call it. But where Madoka Magica merely redeemed magical-girls anime, Sasami-san@Ganbaranai attempts the even harder task of attempting to redeem a story about a shut-in girl and incestuous fanservice.
