So, I went to this show last night, it came through Albuquerque on its world tour, and I have to say, it's really great. It is based off of the tv show of the same title(just take off "movie"), and the tastiest way I can think of to describe them for people who haven't seem the series, or the movie; Take "Sailor Moon", reduce everyone's age about 2-3/4-5, years. Through in some Crack, sprinkle on some shrooms, and soak in Acid.
No, it's an anime movie that is based off of the series. You can order it here: Madoka Magica USA Official Website, News and Trailer
