This is an excellent film and I highly recommend it. The imagery and soundtrack is lush, and the story focuses intensely on Camille's perfectionism and fortitude, all the while depicting her descent into madness, although some claim she wasn't mad, merely a woman ahead of her time, and thus ostracized.
From what I have read of various biographies of Camille Claudel, I understand that she was a woman ahead of her time; she scorned the bourgeois, just as many artists, writer, and musicians did -- in the same way that modern artists scorn the common, small-minded, and narrow society (read Hermann Hesse's Steppenwolf for a good understanding of the artist's situation in society).
Following the pattern of Vincent van Gogh and Franz Schubert, Camille Claudel was not a great "promoter" of her works, and, to make things worse, the bourgeois society, just like today, failed to understand her art (again, like the plight of Vincent van Gogh and many others).
At her core, Camille Claudel was a true rebel, not because she wanted to be, but because she had to. Camille Claudel was a true artist, in the very deepest sense.
