I watched this movie and I couldn't help but laugh at most of the claims they make. As you have said, plenty of people have already debunked most of the crap they spew in the movie. Here are a few examples:
It is actually quite irresponsible to promote a nutrient deficient diet like this. If you want to follow a vegan diet for ethical reasons (however misguided they might be), then so be it. But surviving on a vegan diet requires a serious amount of careful effort and supplementation to get enough nutrients to live a healthy life.

Funny how they leave out small little details like the example of the Connor McGregor vs. Nate Diaz fight. McGregor was scheduled to fight an opponent at a lower weight class and that opponent pulled out of the fight last minute. Connor was preparing for a fight in the 70kg lightweight class, but then at the last minute had to put on weight to fight Nate in the 77kg welterweight class. That is a jump of two weight classes. Conveniently, they didn’t mention that in their second fight, McGregor beat Nate at 78kg.
The kicker of course, is the fact that the Camerons are heavily invested in a fake meat company, so is Lewis Hamilton and most of the actors in the movie have some sort of commercial interest in promoting veganism.
It's telling that while watching the documentary, I realised that this kind of opinions and these kind of refutals would be all over the internet. It's sort of like the EFF attacking the Boks. No matter what the message is on any subject, there is always a group of people who will argue the opposite. And so it is.
But it has been quite pleasing to see that the number of criticisms are quite limited on the case of this documentary, and even many of the ones that argue against it, still concede the message is quite important. Namely, eat less meat and more veg. And that is for any number of reasons, not just our own personal health.
As with any science, you will of course get someone arguing the opposite. That's ANY science, but particularly food science, as we have seen with lots of these types of documentaries. Give me a Tim Noakes, I'll give you 5 scientists who say exactly the opposite. As we have with your first link, refutals of the science by a clever guy. Mind you, he's presenting and referencing studies in the same way the movie did, and I'll bet any money that some other scientist with an opposing view could come along and do to his opinion what he just did to this movie.
Personally, there is a lot of good info to be taken from any movie like this, if you want to that is. But I suppose it's down to the individual approach and knowing where to read between the lines. I just don't get why you or anyone else would be so scathing and label such stuff as "crap" and 'laughable", while at the same time choosing to believe a few other random peoples blogs? Unless you of course enter watching such a movie with a closed mind and you simply want to reinforce your world view.
And if your view is that the multi millionaires in the documentary are trying to deceive us so they can make a few bob on the side, then I'd say you already had your answers long before you watched it.
