I just saw the movie and i was curious what rating it has on IMDb, can't say i am surprised.
Fortunately there aren't many reviews so i read all of them just to get an idea.
Debates are always positive, unless both parties are wrong. I like when a documentary leaves me slightly conflicted because i go to the reviews in hopes to find that random extra information i need to sway me into a certain direction but to be fair, these days is getting increasingly hard to find a documentary which is 100% unbiased or 100% accurate facts and it's our own societal/governmental evolution or rather "devolution" to blame for that.
Everything now has hundreds of entities that "govern" everything in-between, like the LGMA, no one knows who is doing what for who or who's to be blamed if things go (-) (-) up, but in practice we kind of all know that most are doing it for their own self existence, the old "getting paid by the company that you should investigate" conundrum is as old as time and just like sugar has now 999 different names on a label, it's getting harder to even know who's who.
I'm actually amazed that this docu' managed to pull the Purdue guy, LGMA guy and that "scientific" lady only to roast them.
There is always mostly one big lesson i learn and consolidate from a slew of very different documentaries, and that is the LAW, the GOV, the companies, never did or ever will care about what happens to us, and that there are a thousands companies getting bribes and salaries for no apparent reasons except play some make believe intermediaries, oh and also wash you leafy greens and cook your meat!
