While the title and subject of the movie had the potential of a great drama, the result is far from interesting, as if the topic of anorexia itself is not touched, for some obscure reasons. By trying to be original, the film only vaguely scratches the surface of its subject.
In a way, "To the Bone" is quite similar to the feeling of its main character, who doesn't openly explain what she is feeling.
Finally, its conclusion makes no sense.
I give the movie 3 out of 10. Boring.
