How effective IYO was Morgan Spurlock (RIP) the activist filmmaker ("Supersize Me", [0]) at trying to educate the general (meat-eating) US public on US meat production, the restaurant industry, nutrition, marketing?
(PS:it's not a dichotomy between strict vegetarianism vs meat 4+ days/wk. Can encourage people to eat healthier and more sustainable.)
Can't just dismiss his 17 films as a grift. Even accepting all the valid criticisms where he misled audiences, his shockumentaries did try to educate, somewhat, but also stretched facts and went for a personalized narrative, Michael-Moore-style. He did leave a legacy of nearly single-handedly reviving documentary as a film genre relevant to nutrition, one that mainstream audiences would watch.
His sequel "Super Size Me 2: Holy Chicken!" (2017) had fewer distortions and was pretty watchable and educational. Here's a review from https://www.agdaily.com/livestock/poultry/super-size-me-2-mo... which among other things covered in depth: "Many food labels, such as organic, natural, non-GMO, gluten-free, no added hormones, free range, green, artisan, antibiotic-free, are indeed quite misleading" and how those branding terms are misused in marketing to restaurant customers. I haven't seen any industry criticism of the segment with the two branding consultants.
As to the legacy of "Super Size Me", here's a review by an ag evangelist: https://www.eater.com/24173039/morgan-spurlock-legacy-super-...
I mean I’m not an expert but I think the general sentiment among Americans about meat is “yeah I hear meat production is gross/polluting/inhumane but I like meat and don’t want to think about that”. Charitably I think we have a lot of things we can care about and most people want to ignore this, plus there’s a lot of cultural baggage tied to diet people don’t want to leave. I think actual solutions will mostly involve the idea that reduction is good instead of throwing up your hands because you’re unable to commit to being vegan, and adding options to people’s diet that they actually enjoy. I think we have a very hard time solving “I can’t completely solve this and also it requires changes I don’t like so doing nothing at all is fine”.
