Madoka Magica is an anime about magical girls. It takes an interesting view at the whole "magical girl" genre and gives it a nice new vibe. It's different and pretty fun, but can get dark at times. It also has an outstanding soundtrack. It's beautiful.
Short synopsis:
Madoka Kaname and Sayaka Miki are regular middle school girls with regular lives, but all that changes when they encounter Kyuubey, a cat-like magical familiar, and Homura Akemi, the new transfer student.
