I skimmed the first episode of Mahou Shoujo Madoka★Magica and I can only say, holy cr@p. The picture on the chart, and all promo material I've seen suggest a completely generic magical girl show, but I was pretty blown away by the first two minutes. Those two minutes completely hooked me into this show more than the entire first episodes of some of the other shows I've watched.

There's Yuki Kajiura composing the soundtrack, then you have Shaft (Bakemonogatari, and Zetsubou Sensei) doing the animation, with its typical craziness, though its toned down a bit.
