Pandemic: The People, the Conspiracy, the Journey

One reason (amongst many) not to watch it: if you consider your time valuable, run away. This is a heap of conspiracy theories of the worst kind. It would induce people not to watch after themselves or others in order to make money for the makers of this film and other Alex Jones.

One reason (the only one) to watch it: If your sense of humour makes you giggle at people who think you are dumb enough to believe anything quoted as "facts" in a work of fiction pretending to be a "documentary".

But even as an anti-vaccines conspiracy vehicle, this is bad, despite competition for worst nonsense being widely available. It manages to be both pretentious and simplistic which is an achievement in itself.
