I saw this movie more or less by the middle of 2007 and I must say it was a powerful film to me. I was surprised by it. It's a very different story to those I am more used to watching.
First, it is about a real life person's life. This made me feel almost like it was a documentary spoken in the first person. The main characters are so very human (good and bad, which is a big difference in comparison to other less personal films. The protagonist, Marjene, is a girl (then woman) who just has problems in her life but can only do so much to overcome them, yet she does what she can (not avoiding making mistakes in that process).
Also the animation was pretty good for a relatively low budget. The black and white suits the movie well.
I couldn't tell you whether the voice acting was good because I saw it in Spanish (and it was OK), but I don't know if the English version will have the same treatment.
Overall, I'd recommend watching this movie to everyone who is interested in people from a part of the world that are only seldom portrayed in animation.
