The OP also misses the substance of the critique. It wasn't the just the nutritional value of the food, it was the serving sizes and the upsell to larger sizes (he super sized only when prompted). Add in some ahead of its time commentary on food deserts, and it was a rational critique of systemic issues.

Yep, there was a vague acceptance of calories and poor nutritional value, but everyone kinda ignored it, I think we thought we could maybe get away with it. 

The same thing that happened with tobacco in the 1970s. Everyone kinda laughed and said "yeah I guess it'll kill me eventually" but you could tell they just didn't really believe it. 

Supersize Me was the first thing I saw that was like "no really, this *will* kill you"
