Out of the three Rozen Maiden's I think that this one has the darkest tone. Separating from the light tone of the first season and the beginning of the second season is something the show needed. Having this overture to the show added more effect to a certain character if you go, and watch the second episode. Overall it is amazing and for less than an hour to watch is something most anyone watching Rozen Maiden should watch. I think that it is even better than the first season, and on par with the second. The only thing is that if you watch this afterthe first seasons before the second the entire show makes more sense. So I think that for the one hour that it takes to watch it is definitely worth it.
