If you're someone who has (or suspects you have) an eating disorder, then I would certainly recommend that you give "Thin" a serious view.
This documentary certainly does open one's eye to how really critical this problem is in the USA, alone. It's estimated that eating disorders affect millions (especially teen-aged girls) all across the American nation, and beyond.
The one thing that I found to be on the somewhat ironic side of "Thin" was that a number of the employees (both men and women) who worked at the Renfrew Center (where a good portion of this documentary was filmed) were, indeed, grossly overweight. This, in turn, showed yet another form of eating disorder and greatly contrasted the super-thin look of the patients who were in residence there.
All-in-all - I found a good part of this documentary to be on the depressing side, and so, in the long run, I wasn't able to fully appreciate the grave message that it was trying to deliver.
