Higurashi no Naku Koro ni ep 01
A mixture of creepiness and moe, based on a series of doujin visual novels. I'm watching this mostly for the doujin angle, because I'm such an otaku but also because any doujin work that actually gets the anime treatment is bound to be pretty good.
So far, it has pretty simplistic art, which is probably true to the original, some mildly amusing moe, and hints of darkness that could maybe be a little more subtle. Hard to say which way it will go from here, but if Sling is right about it getting creepier, so much for the better.
The opening theme is totally awesome. It reminds me of the good version of the Fate/Stay night theme used in the game (as opposed to the horribly bland theme used in the anime).
