Herm...I feel where going to have to disagree on Shigurui, Oaxaca. I thought it was one of the worst anime I had ever seen. Bet different strokes.
Have fun with Madoka Magica though, when you get past the flowery exterior it's one of the most harrowing anime of recent years at time's.
And thanks for the recommendation on Mardock Scramble, heard good stuff about that one.
