Les Miserable's: Shoujo Cosette
Based off of the novel I presume. I haven't actually read the book, or watched the movie or the play. However, it has a feel of a Disney classic (albeit, much longer, its about 50 episodes).
The characters aren't incredibly deep on their own, but their interactions with each other is what makes it what great. It reminds me of baccano in that sense.
Summary: A mother and daughter, Fantine and Cosette, have left Paris and are travelling the french countryside as the mother looks for work. A sly inkeeper swindles Fantine into leaving her daughter in the care of him and his wife, in exchange for pay. The story then unfolds into the struggles and interactions of a large cast of characters in a poverty stricken France.
I haven't finished watching it myself, but I am in the process of marathoning it. I've been hooked since the first episode, and it will probably end up in my top 10.
