I just finished watching it. I thought the plot line was well put together. I don't recommend this to people who like funny animes. There are only 2 comic relief episodes in the two seasons of this show.(1 for the first season and 1 for the second season) I do recommend this to people who like dolls, supernatural forces, and people who are afraid to leave their house because of some type of embarrassment. Here's the article: http://en.wikipedia.org/wiki/Rozen_Maiden
Ooo~ It was a good anime... though I didn't get to finish it due to school and job and etc... but now that I have some free time, I think I'll go watch it again. It's a serious anime [sort of], and I liked that, it's sort of a far leap from regular animes. Good show. ^_^-
I need to look into it. Found out I had the opening on my iPod for some time. XD That's how I look into anime. I accidently get the opening, I get curious, then I watch, then I like.
